In order to investigate the adsorption performance of black fungus bran biochar on Cu2+, Cd2+ and Pb2+ in water, waste black fungus bran was used as raw material to prepare black fungus bran biochar by oxygen-limited pyrolysis at 350?, 550? and 750?, then the adsorption experiments were conducted at different pH, reaction time and initial concentration. Thus, the adsorption performance of Cu2+, Cd2+ and Pb2+ was investigated by different pH, reaction time and initial concentration.
