Cellulose-based adsorbents received growing interest in the field of heavy metal and organic wastewater treatment, as they have the advantages of being abundant in quantity, widely available, inexpensive, and renewable. This paper reviewed the research on heavy met al and organic pollutant removal by cellulose-based adsorbents in the aspects of adsorption processes and adsorption models. The logical relationships among adsorption processes, adsorption models, adsorption mechanisms, and adsorption performance were also discussed. Finally, the existing problems of cellulose-based adsorbents in the fields of heavy metal and organic wastewater treatment were summarized. The prospects for real-world application were also proposed. [ABSTRACT FROM AUTHOR]

The degradation properties of poly(lactic acid)(PLA) mulching film and its effects on soil and crops were studied in this paper. The comparison experiments based on watermelon production were conducted with PLA mulching film and traditional non-degradable PE mulching film. The results showed that the PLA mulching film firstly appeared cracks, then holes and breaks in the end during the degradation process. The PLA mulching film had more favorable heat preservation effect, and there were no significant differences in the content of soil heavy metals and metal oxidation of main elements in the process of watermelon growth between two mulching films. The impacts of two different mulching films on watermelon stem diameter and length had no significant differences, while the watermelon seedlings, leaves number and chlorophyll content of the PLA mulching film group were higher than that of the traditional non-degradable PE mulching film group, however the watermelon production had no significant differences. The PLA mulching film with good degradation is expected to replace the traditional mulching film in the field. It will reduce the soil pollution caused by agricultural film and accelerate the development of modern ecological agriculture. [ABSTRACT FROM AUTHOR]
