Synthesis and characterization of sugarcane bagasse ash with chitosan composite by batch adsorption studies

Textile effluents, containing high concentrations of synthetic dyes, pose significant environmental hazards due to their toxic, carcinogenic, and mutagenic properties. These dyes contribute to serious water pollution because of their intricate aromatic structures, which make them resistant to traditional water treatment techniques. This study focuses on creating a novel adsorption method for removing synthetic colors like Methylene Blue (MB) from aqueous solutions by doping chitosan with sugarcane bagasse ash. Sugarcane bagasse ash is added to chitosan, a naturally occurring poly-amino saccharide, to increase its adsorption potential. FTIR, TGA, SEM, TEM, and BET analysis are used to examine the structural, thermal, and morphological properties of the composite. The findings suggest that the sugarcane bagasse ash with chitosan composite is a feasible and economical way to treat dye- aqueous solutions since it has a significant bandgap value and superior catalytic characteristics when compared to chitosan alone. This strategy offers a sustainable way to use agricultural waste in addition to addressing water contamination. published by the Journal of Biodiversity and Environmental Sciences (JBES)
