Abstract

Biochar, a byproduct of thermochemical transformations such as pyrolysis from green waste, can be used in numerous environmental applications, such as the treatment of water contaminated with toxic metals, due to its high adsorption capacity.  Therefore, this study investigated the use of metalized biochar, derived from legal Amazonian residual biomass (Baru and Cupuaçu), for the removal of chromium (VI) from aqueous solutions. The biochar was characterized, and its adsorption capacity was evaluated using a central composite design (CCD) experimental plan. The results showed high efficiency in Cr(VI) removal (>98% for initial concentrations of 5 mg/L and >99% for 20 mg/L), at various pH levels and biochar dosages. This sustainable approach offers an economically viable and environmentally friendly solution for managing agricultural waste and remediating chromium-contaminated water.
