Highlights The production, physicochemical properties, and As adsorption mechanisms of pristine and modified biochars were reviewed. Pyrolysis temperature, pH, presence of dissolved organic carbon, surface charge, and microbial activity affect the As adsorption. Modified biochars show promise for As adsorption due to combined mechanisms of complexation, ion exchange, oxidation, and reduction.
