Abstract
The leather industry, often criticized for its substantial contribution to environmental pollution, has frequently overlooked the removal of organic contaminants from its wastewater. In response, this study aimed to revolutionize the treatment of tannery effluent by fabricating GO-CS-AgNP nanocomposite with noticeable adsorption efficiency for organic pollutants. Rigorous analysis, including XRD, TEM, SEM, FT-IR, and UV–Vis spectroscopy, provided a comprehensive understanding of the physico-chemical properties of GO-CS-AgNP nanocomposite. To optimize its adsorption performance, several parameters were carefully considered, including pH levels, optimal dosage, and contact time respectively. Surprisingly, employing just 0.12 g/L of the nanocomposite and 50 min of stirring at a pH of 6.0 produced highly promising adsorption results of pollutants, as evidenced by UV–Vis Spectroscopy at 450 nm. Notably, GC–MS analysis revealed an impressive 94.05 % removal of total organic pollutants, coupled with substantial reductions of 85.94 and 62.63 % in BOD and COD, respectively. Furthermore, the nanocomposite exhibited efficacy in removing potentially toxic metals. The findings of the study underscored the adherence of GO-CS-AgNP nanocomposite to the Freundlich isotherm model and a pseudo-2nd order kinetic reaction, establishing it as a sustainable and effective solution for minimizing pollution in the leather industry without compromising the environment, representing a significant leap toward more environmentally conscious tannery practices.
期刊介绍：
Environmental Nanotechnology, Monitoring and Management is a journal devoted to the publication of peer reviewed original research on environmental nanotechnologies, monitoring studies and management for water, soil , waste and human health samples. Critical review articles, short communications and scientific policy briefs are also welcome. The journal will include all environmental matrices except air. Nanomaterials were suggested as efficient cost-effective and environmental friendly alternative to existing treatment materials, from the standpoints of both resource conservation and environmental remediation. The journal aims to receive papers in the field of nanotechnology covering; Developments of new nanosorbents for: •Groundwater, drinking water and wastewater treatment •Remediation of contaminated sites •Assessment of novel nanotechnologies including sustainability and life cycle implications Monitoring and Management papers should cover the fields of: •Novel analytical methods applied to environmental and health samples •Fate and transport of pollutants in the environment •Case studies covering environmental monitoring and public health •Water and soil prevention and legislation •Industrial and hazardous waste- legislation, characterisation, management practices, minimization, treatment and disposal •Environmental management and remediation
