Abstract

While various techniques have been explored for the sequestration of heavy metals such as copper from industrial effluent, there is enormous research on the use of biosorbents created from bio-waste in the environment for the confiscation of Cu(II) ion owing to their low cost and green nature. In this study, a biochar-NH2 biosorbent synthesized from watermelon peels was explored for the elimination of Cu(II) ion from water-soluble solutions. The synthesized biochar-NH2 was further characterized using FTIR, BET, and SEM coupled with EDX to ascertain the present functional groups, the surface area, morphology, and elementary composition of the biosorbent. The determined biochar-NH2 BET-specific surface area and the total pore volume were 12.26 m2/g and 0.012 cm3/g. The differential thermal analysis (DTA) of the WWP and biochar-NH2 samples showed six peaks at flow temperatures of 769, 178, 251, 292, 426, and 872 °C, and two distinct degradation peaks at flow temperatures of 767 and 477 °C. The sequestration of Cu(II) was noted in this study to be dependent on the pH, with the best possible confiscation of Cu(II) ion noticed at pH 5.6. The process of Cu(II) adsorption to the biosorbent was perfectly defined utilizing the Langmuir (LGR) and pseudo-second-order (PSO) models with correlation coefficient (R2) values of 0.944 and < 0.99. It is implicit that the sorption process consists of a chemisorption process in rate-limiting stages. The determined sorption capacity estimated from the Langmuir isotherm model was determined to be 140.85 mg/g and when the sorption capacity of biochar-NH2 was compared to other biosorbents employed for the sequestration of Cu(II) ion from water-soluble solutions, the biochar-NH2 biosorbent was found to be an effective biosorbent for Cu(II) elimination. Additionally, it was found that the biosorbent can be regenerated up to six regeneration cycles for the confiscation of Cu(II) ion. In conclusion, it was discovered in this study that the synthesized biosorbent was a cost-effective adsorbent with a high adsorption efficacy for Cu(II) removal. [ABSTRACT FROM AUTHOR]

Abstract

Presently, hazardous metal and dye removal from wastewater is one of the major areas of research focus. For the elimination of these contaminants, many approaches have been devised and applied. However, the accomplishment of various water treatment processes has largely depended on the medium utilized and the associated problem with the leaching of harmful compounds into the water process with most commercial and chemically manufactured materials for water treatment processes. Hence, this study is aimed at reviewing existing studies on the sorption of heavy metals (HMs) and dyes using bionanocomposites (BNCs). The key focus of this review is on the development of eco-friendly, effective, and appropriate nanoadsorbents that could accomplish superior and enhanced contaminant sequestration using BNCs owing to their biodegradability, biocompatible, environmentally friendly, and not posing as secondary waste to the environment. The sorption of most pollutants was observed to be pH, sorbent dosage, and initial contaminant concentration-dependent, with most contaminants’ elimination taking place in the pH range of 2-10. The sorption process of HMs and dyes to various BNCs was superlatively depicted utilizing the Langmuir (LNR) and Freundlich (FL) as well as the pseudo-second-order (PSO) models, suggestive of the sorption process of a monolayer and multilayer and the chemisorption process, the rate-limiting stage in surface sorption. The established sorption capacities for the reviewed sorption process for various contaminants ranged from 1.47 to 740.97 mg/g. Future prospective for the treatment and remediation of contaminated water using BNCs was also discussed.

Abstract

Presently, with the introduction of nanotechnology, the evolutions and applications of biosensors and/or nanobiosensors are becoming prevalent in various scientific domains such as environmental and agricultural sciences as well as biomedical, clinical, and healthcare sciences. Trends in these aspects have led to the discovery of various biosensors/nanobiosensors with their tremendous benefits to mankind. The characteristics of the various biosensors/nanobiosensors are primarily based on the nature of nanomaterials/nanoparticles employed in the sensing mechanisms. In the last few years, the identification, as well as the detection of biological markers linked with any form of diseases (communicable or noncommunicable), has been accomplished by several sensing procedures using nanotechnology vis-à-vis biosensors/nanobiosensors. Hence, this study employs a systematic approach in reviewing some contemporary developed exceedingly sensitive nanobiosensors alongside their biomedical, clinical, or/and healthcare applications as well as their potentialities, specifically for the detection of some deadly diseases drawn from some of the recent publications. Ways forward in the form of future trends that will advance creative innovations of the potentialities of nanobiosensors for biomedical, clinical, or/and healthcare applications particularly for disease diagnosis are also highlighted.

Abstract

The adsorption of Cr6+ ions from water-soluble solution onto activated pea peels (PPs) embellished with triethylenetetramine (TETA) was studied. The synthesized activated TETA-PP biosorbent was further characterized by SEM together with EDX, FTIR and BET to determine the morphology and elementary composition, functional groups (FGs) present and the biosorbent surface area. The confiscation of Cr6+ ions to activated TETA-PP biosorbent was observed to be pH-reliant, with optimum removal noticed at pH 1.6 (99%). Cr6+ ion adsorption to activated TETA-PP biosorbent was well defined using the Langmuir (LNR) and the pseudo-second-order (PSO) models, with a determined biosorption capacity of 312.50 mg/g. Also, it was found that the activated TETA-PP biosorbent can be restored up to six regeneration cycles for the sequestration of Cr6+ ions in this study. In comparison with other biosorbents, it was found that this biosorbent was a cost-effective and resourceful agro-waste for the Cr6+ ion confiscation. The possible mechanism of Cr6+ to the biosorbent was by electrostatic attraction following the surface protonation of the activated TETA-PP biosorbent sites. [ABSTRACT FROM AUTHOR]
