Water-repellent soil has a very wide application prospect in the field of agricultural engineering. However, it is still lacking in the hydraulic stability of water-repellent clay. The applications are only targeted at water-repellent dry sand so far. In this study, octadecylamine was taken to modify the highly adsorbent expansive soil with water repellency. A systematic investigation was also conducted to explore the water-repellent and hydraulic stability of loose expansive soil with different water repellency after adsorbing water vapor. Five samples were selected as the compacted expansive soil (hydrophilic expansive soil, hydrophilic expansive soil + hydrophilic sand, hydrophilic expansive soil + water repellent sand, water repellent expansive soil, water repellent expansive soil + water repellent sand). The results show that the greater the humidity was, the greater the mass of water vapor adsorbed by different water repellency expansive soil was. At the same humidity, the water repellency shared little effect on the mass adsorbed by soil. The expansive soil with different water repellency (including slight water repellency) was extremely water repellent after adsorption, where all test points were evenly water repellent. The huge specific surface area of water-repellent expansive soil was obtained for the strong adsorption properties. As such, the water repellency of expansive soil further increased to fully adsorb octadecylamine molecules while adsorbing water vapor during adsorption. After compaction, the water-repellent expansive soil and water-repellent expansive soil + water repellent sand samples exhibited water repellency in a large range of moisture content. There was a range of water-repellent moisture content, all of the soil samples were extremely water-repellent. Compared with the rest, the best hydraulic performance was achieved in the water-repellent expansive soil + water-repellent sand mixed sample share. Specifically, the expansion rate of the expansive soil was reduced from 33.9% to 3.45%, and the shrinkage fissure degree was reduced from 18.75% to 3.6%. Hydrophilic expansive soil realized 90% of the expansion within 90 min, while it took 1 680 min for water-repellent expansive soil and water-repellent sand to complete the same proportion of expansion. Water-repellent modification of expansive soil reduced the expansion amount and rate. There was the basically same air entry value of the hydrophilic sample and the water-repellent sample. But the water content corresponding to the air entry value of the water-repellent sample was smaller than that of the water-repellent sample, and the water-repellent expansive soil matric suction followed the same trend as hydrophilic expansive soil, in terms of moisture content. The pore water pressure remained "negative" at all times in the extremely water-repellent expansive soil, as the moisture content changed. There was no "positive" pore water pressure. There were the lower strength parameters c and φ of water-repellent expansive soil, compared with hydrophilic expansive soil. There was no significant change, indicating better mechanical properties after water-repellent treatment. The special hydraulic properties of waterrepellent expansive soil were attributed to that the water-repellent aggregates remained dry inside the aggregates after immersion. This finding can provide a new idea for the application and promotion of water-repellent clay in agricultural engineering. An experimental basis can be offered to fully expand the application scope of water-repellent soil. [ABSTRACT FROM AUTHOR]

BACKGROUND: It is of great significance for evaluation, early warning and remediation of antimony contaminated soil to study the sorption factors affecting Sb(Ⅲ) adsorption in soil. OBJECTIVES: To investigate the forms of Fe and Mn oxides and controlling factors of Sb(Ⅲ) adsorption in soil. METHODS: The physicochemical properties, mechanical composition, and main chemical composition of soils from 10 different areas were determined by chemical method, inductively coupled plasma - optical emission spectrometry and atomic fluorescence spectrometry. The contents of different forms of iron and manganese and the saturated adsorption capacity of soils to Sb(Ⅲ) were determined by atomic absorption spectrometry. The correlation analysis, principal component analysis and factor analysis of soil saturated adsorption capacity to Sb (Ⅲ), soil physicochemical properties, mechanical composition, iron and manganese oxides and their forms were carried out by SPSS 21. 0. RESULTS: On the basis of studying the influencing factors of soil adsorption of Sb(Ⅲ), the main controlling factors were further studied. The saturated adsorption capacity of soil to Sb (Ⅲ) was between 0. 63mg / g and 3. 98mg / g, and was related to soil type with the order of red soil>brown soil>yellow soil>cinnamon soil>sandy soil. According to the correlation analysis results, the saturated adsorption capacity of soil to Sb(Ⅲ) was significantly positively correlated with cation exchange capacity, total iron oxide, amorphous iron content, and was positively correlated with free iron content, amorphous manganese content and free manganese content. The principal component analysis and factor analysis showed that these six factors were the main controlling factors affecting the adsorption of Sb(Ⅲ) in soil, and the influence degree was: total iron oxide>cation exchange capacity>amorphous iron content>free iron content>amorphous manganese content>free manganese content. CONCLUSIONS: The adsorption capacity of soil to Sb(Ⅲ) is significantly affected by the total amount of iron and manganese oxides and their forms. [ABSTRACT FROM AUTHOR]

The low density of surface functional groups and the lack of adsorption capacity for negatively charged heavy metal ions are the disadvantages of mussel biomimetic chemical preparation materials. In order to solve the above problems, a dopamine quaternary ammonium salt non-woven fabric adsorbent was prepared by a quaternization method. The adsorption experiment results showed that the maximum adsorption capacity of Cr (Ⅵ) was achieved at pH=3, and the removal efficiency reached 95%. The theoretical maximum adsorption capacity obtained by fitting was 31.92 mg/g. The XPS results showed that the adsorption of Cr (Ⅵ) was related to the quaternary ammonium salt groups and protonated amino groups. In addition, the quaternary ammonium improved the regeneration performance. Dopamine quaternary ammonium salt non-woven show broad application prospects in the field of Cr (VI) adsorption and removal. [ABSTRACT FROM AUTHOR]

ZnO/HNTs nano composites are prepared by in-situ growth of ZnO nanoparticles on the surface of halloysite nanotubes (HNTs) using zinc nitrate as zinc source. The ZnO/HNTs are characterized by X-ray diffraction, scanning electron microscope, X-ray energy spectrometer, specific surface area and porosity analyzer, UV visible near infrared diffuse reflectance, and ZetaSizer Nano 9() dynamic light scattering (T)LS) particle size analyzer tester. The adsorption and photocatalytic degradation performance of HNTs, nano-ZnO and ZnO/HNTs composite materials for methylene blue (MB) under UV illumination are investigated. The results show that the nano-Zn() is evenly distributed on the surface of HNTs. Compared with nano-Zn(), the specific surface area of ZnO/HNTs is as high as 44.305 m2/g, which is 1.2 times higher. For ZnO/HNTs, the degradation rate of 1 5 mg/L methylene blue with degradation time of 1.5 h is close to 1()()%, which is much higher than that of nano-ZnO (80.2%), and its repetitive catalytic efficiency maintains remains 80.4% after 10 cycl es. Tt is shown that the introduction of HNTs greatly improved the catalytic activity of ZnO/HNTs. [ABSTRACT FROM AUTHOR]

In order to study the heavy metal pollutant adsorption of sediment under the phase-separation model, based on the Langmuir isothermal equation, the sediment and heavy metal phases were regarded as two phases and the adsorption process was numerically simulated through two calculation methods: time-step method and UDS method. Firstly, the sediment adsorption process under seven turbulence models was simulated by combining component transport model with UDF using commercial software fluent. The results were compared with the Langmuir model, the feasibility of the method was verified and the model with the highest consistency was selected. Secondly, the adsorption capacity of sediment particles under different sediment concentration and particle size were obtained by using the selected model. And the change trend of cadmium ion concentration in aqueous phase was simulated. The results show that the sediment concentration directly affects the adsorption of water, the smaller the concentration, the weaker the adsorption, the slower the adsorption rate is, the less the concentration is and the less the adsorption can be. The adsorption effect of sediment particle size in water is obvious, but it cannot determine the amount of sediment adsorption. Both UDS and time-step methods have advantages and disadvantages in calculating the adsorption amount under the influence of particle size. The results of the dynamic time obtained by the stepwise method are more appropriate and the numerical results of the adsorption amount obtained by the time-step method are in better agreement with each other.

[Objectives] Two cadmium-tolerant microorganisms were isolated, and their adsorption and immobilization characteristics of cadmium were explored preliminarily. [Methods] In this study, cadmium-tolerant microorganisms were isolated with a series of cadmium-containing solid media, and I6S rKNA gene sequencing was performed to identify the bacteria. Two strains were cultured in LB liquid culture with 50 mg·L-1 cadmium, and D600 value, pH value, and extracellular polymerization were monitored during the incubation. The different mechanisms of cadmium adsorption and immobilization were studied. [Results] Two strains with strong cadmium tolerance were isolated, and grew well under 600 mg·l-1 cadmium in LB plate. They were identified as Achromobacter sp. (ZXH21)and Pseudomonm sp.(ZXH23)by 16S rHNA gene sequencing. Both strains had certain cadmium adsorption and immobilization ability under 50 mg·L-1 cadmium treatment, and the cadmium removal efficiency was similar. The maximum removal of cadmium by ZXH21 and XXH23 were 36.5% and 33.7% respectively. The removal mechanism of cadmium by both strains was main ly extracellular adsorption, with absorption as a supplement, however, the rate varied. At 72 h. the adsorption and absorption rates of ZXH21 were 25.3% and 0.6% respectively, and those of ZXH23 were 30.6% and 0.1%. Thf : absorptivity of the two strains were quite different, and ZXH2I was 6 times higher than that of ZXH23. [ Conclusions] ZXH21 had stronger cadmium tolerance and more stable removal potential than ZXH23. The main mechanism of cadmium removal by ZXH21 was by the biomass increment and the secretion of solu. ble polysaccharides. Surface adsorption, secretion of insoluble proteins and insolubl c polysaccharides might be the main factors for the cadmium removal of ZXH23. [ABSTRACT FROM AUTHOR]

Triethylenediamine(DETA)was used as a reducing agent and structural enhancer to prepare ultra-elastic graphene aerogel(GA)by means of hydrothermal reduction method. The realationship between the properties of GA and the mass concentrations of GO and DETA were studied. The microstructures and properties of GA were characterized by X-ray diffraction(XRD), four-point probe, scanning electron microscopy(SEM), universal tensile testing machine and absorption measurement, respectively. The density and conductivity of GA vary with mass concentrations ratio of GO to DETA. The compressive strength increases with increasing mass concentrations ratio of GO to DETA. The maximum compressive strength is up to 6. 8 MPa when the concentration of GO reaches 8 mg/mL and the mass concentration ratio of GO to DETA keeps at 1 000:7.5. Besides, GA can recover its shape completely after compression, showing good anti-fragile performance. As confirmed from the brightness of Light-Emitting Diode(LED)light, the larger compression strain was, the better conductivity would achieve. In addition, absorption behavior of GA towards seven organic solvents was studied. It is presented that GA could absorb these liquids at 41 to 83 times of its own mass requiring no further pretreatment, showing highly efficient absorption feature of organic solvents.

Shale gas mainly exists as a state of absorbed and free in the pores of shale. The multiformity of structures of organic pores makes it difference in the existing state of shale gas. The graphite model was used as shale organic matrix in Materials Studio and two types of holes (rectangle and triangle) in graphite slit were built. Under the condition of 38 MPa and 345 K, the methane densities in different holes and different locations were calculated and the absorption state of methane was studied by using molecular dynamic method.The maximum density of rectangular holes was high up to 0.599 g/cm3 and the value of density was high up to 0.456 g/cm3 in the bottom of the triangle vertex angle, where the densities were above or close to the density of liquid methane. At the same time, the value of radial distribution function in pore was higher than the interface of slit. Finally, the shale samples collected in the field were imaged by scan electron microscope, and then the organic matter boundary can be identified clearly in the SEM images. Then the first and second absorbed layers were outlined in the image of the studied area. Based on the simulation results of density distributions,the possible shale gas content was calculated.

Biochar is a kind of carbon-rich solid material obtained from biomass resources, which can be used as source of energy, catalyst, adsorbent and soil conditioner. Bamboo is a kind of widely used biomass resource containing high fraction of lignocellulose, and bamboo waste from industrial processing is a kind of good raw material for producing biochars. Hydrothermal carbonization approach was applied at low temperatures to produce bamboo biochars, and the selected biochar samples were further modified by being immersed in the sodium hydroxide (NaOH) solution or calcined in nitrogen atmosphere. The effects of the preparation conditions on the physico-chemical properties of the bamboo biochars were investigated, and the adsorption properties of the biochars for 2-naphthol and Congo red from their aqueous solutions were evaluated. The results showed that the yields of the bamboo biochars from hydrothermal carbonization without modification were between 54.12% and 71.53%, and the functional groups containing oxygen such as -OH (3 200-3 600 cm-1), C=O (1 650-1 735 cm-1) and C-O (1 000-1 250 cm-1) were found to be rich on the surfaces of these biochars; the oxygen content of the bamboo biochar produced at 200 ℃ and 7 h was as high as 46.33%, and the surface area of the same carbon sample was measured to be 14.10 m2/g. The bamboo biochars modified by being immersed in the NaOH solution still showed rich oxygen-containing groups on their surfaces, high yields were also achieved with these samples, much larger surface area (33.22 m2/g) was obtained for the biochar sample produced at 200 ℃ and 7 h and modified by soaking in NaOH solution for 1 h, and the oxygen content of this carbon sample was 50.57%, which was higher than that of the sample before modification treatment. On the other hand, few functional groups were found on the surfaces of the bamboo biochars modified by calcination in nitrogen atmosphere, the yields of these biochar samples were much lower (between 12.99% and 16.21%), even higher surface area (52.39 m2/g) was observed for the biochar sample produced at 200 ℃ and 7 h and modified by calcining in nitrogen atmosphere at 700 ℃, the carbon content of this carbon sample was 75.87%, and the oxygen content of this sample decreased to 20.89%. All of the bamboo biochar samples without modification treatment could adsorb 2-naphthol and congo red from aqueous solutions, of which the sample produced at 160 ℃ and 3 h showed the largest adsorption capacity for 2-naphthol (50.3 mg/mL at 25 ℃, initial concentration of 0.5 mg/mL), and the sample produced at 200 ℃ and 7 h showed the largest adsorption capacity for Congo red (63.7 mg/mL at 25 ℃, initial concentration of 0.5 mg/mL), and these 2 kinds of bamboo biochar samples were chosen as the most promising adsorbents for the adsorptive removal of 2-naphthol and Congo red. Surface adsorption was inferred to be the predominant mechanism for the adsorption of Congo red on the surfaces of the bamboo biochars, while a complex mechanism involving partition was suggested for the adsorption of 2-naphthol on the biochars. The NaOH immersion method was favorable for obtaining biochars with higher adsorption capacities for both 2-naphthol and Congo red, and the bamboo biochar sample produced at 200 ℃ and 7 h and modified by soaking in NaOH solution for 1 h displayed the largest adsorption capacities for both 2-naphthol (62.3 mg/mL at 25 ℃, equilibrium concentration of 0.3 mg/mL) and Congo red (69.1 mg/mL at 25 ℃, equilibrium concentration of 0.3 mg/mL). However, calcination in nitrogen didn't show positive effects on the adsorption properties of the bamboo biochars especially for the adsorption of 2-naphthol. The results obtained show that bamboo biochars produced through hydrothermal carbonization can be applied as low cost adsorbents for adsorptive removal of 2-naphthol and Congo red from wastewater.

Retrograded corn amylose is a kind of resistant starch which is formed by the interaction of amyloses through hydrogen bonds. Those bonds hinder the combination of starch and water/amylase, which makes retrograded amylose insoluble and resists amylase hydrolysis. Some of retrograded corn amyloses can form regular crystal with identical characteristic named B-type structure. Such crystal structure provides possibility to absorb organic compounds containing hydroxyls. There are residual carbohydrates, amino acids, water soluble protein and peptides and so on in fermentation broth in the production of monascus red pigments by fermentation liquid method. It is difficult to isolate those substances from pigments in the following process, so the pigments are mixed with impurities in the product. These impurities reduce the degree of pigment purity and bring uncertainties to the stability of pigments in use. The retrograded starch is insoluble in water and contains a lot of hydroxyls, so hydrogen bond can form between starch and hydroxyl-containing pigments or other organic compounds containing a large number of hydroxyl groups. Then the substance containing a lot of hydroxyls is absorbed by retrograded starch, but those ones having no or fewer hydroxyls will stay in solutions. Thus, the component containing hydroxyl groups will be separated from solutions. In this paper, the corn amyloses with different molecular weight distributions were made by retrogradation method and those amyloses were used to absorb monascus red pigments. Absorption capacity and speed of monascus red pigments by those amyloses were determined. The results showed that the maximum absorption capacities of monascus red pigments by amyloses retrograded for 1-4 times were 0.56, 0.84, 1.04, and 1.10 mg/g respectively, when the absorption temperature was 80℃ and the absorption time was 140 h. The narrower the molecular weight distribution of amylose and the higher the absorption temperature, the higher the absorption speed. The average absorption free energies of all samples, which were calculated by Dubinin-Radushkevich adsorption isotherm equation, were less than 8 J/g. Such calculated results suggested that the pattern for retrograded corn amylose to absorb monascus red pigment belonged to physical absorption. The results of the scanning electron microscope (SEM) indicated after drying those retrograded corn amyloses presented some kinds of more bouffant structure when they were combined with monascus red pigments. In order to increase the pigment absorption content of retrograded corn amylose, the regular crystal should be cultured from amylose with the narrowest distribution of molecular weight. So the method of preparing those materials became vital. Only identical amylose with special chain length could involve in retrograded amylose, so amylose with narrow distribution of molecular weight could be obtained by repeated retrogradation. The results of the paper provide a reference for isolating and purifying monascus red pigments with hydroxyls. [ABSTRACT FROM AUTHOR]
