Industries generate hazardous dye wastewater, posing significant threats to public health and the environment. Removing dyes before discharge is crucial. The ongoing study primarily focused on synthesizing, applying, understanding mechanism of green nano-biochar composites. These composites, including zinc oxide/biochar, copper magnesium manganese are designed effectively remove Actas Pink-2B (Direct Red-31) in conjunction with constructed wetlands. Constructed wetland maintained pH 6.0–7.9. At 10th week, oxide/biochar treatment demonstrated highest removal efficiency total suspended solids (72%), dissolved oxygen (7.2 mg/L), (79.90%), followed by other biochar maximum for chemical demand (COD) color was observed at a retention time 60 days. electrical conductivity also same order, decrease up 8th week becoming constant. A comprehensive statistical analysis conducted, encompassing various techniques variance analysis, regression correlation principal component analysis. rate COD second-order first-order kinetics, respectively. negative relationship between COD. indicates that employing composites wetlands improves textile efficiency.

Characterization and spatiotemporal variations of fluorescent dissolved organic matter in leachate from old landfill-derived incineration residues and incombustible waste

Dissolved organic matter (DOM) influences the bioavailability and behavior of trace metals other pollutants in landfill leachate. This research characterized fluorescent dissolved (FDOM) leachate from an old Japan during a 13-month investigation. We employed excitation–emission matrix (EEM) fluorescence spectroscopy with parallel factor analysis (PARAFAC) to deconvolute FDOM complex mixture into three fluorophores: microbial humic-like (C1), terrestrial (C2), tryptophan-like fluorophores (C3). These components were compared findings studies landfills different waste compositions.
