Carbonaceous material from agricultural waste for treating colored wastewater: Characterization and adsorption performance evaluations

Agricultural wastes such as crop residue, livestock waste, agro-industrial waste, and aquaculture waste contribute globally to a massive quantity of municipal solid waste accumulation. Therefore, in recent years, several studies have been directed toward using agricultural waste. They revealed a hig...
