英文摘要	For searching biological material for heavy metal removal of waste-water, using macrofungus Auricularia polytricha as biosorbent for Cu2+ and Pb2+ removal was investigated. After shaking and biosorbing Cu2+ and Pb2+ in solution by biosorbents, the filtrates were tested by AAS and the adsorbed quantity of Cu2+ and Pb2+ was calculated. The biosorbents were effective in removal of Cu2+ and Pb2+ on the biosorbents that showed a highest value around pH 5–6. The biosorption rate of Cu2+ and Pb2+ on A. polytricha biomass decreased with increasing the initial concentration of Cu2+ and Pb2+ in the medium. The biosorption of Cu2+ and Pb2+ on the biomasses follows pseudo-second order kinetics. The determined maximum biosorption capacities presented by the fungus biomass were 3.34 and 13.03 mg · g−1 dry weight for Cu2+ and Pb2+, respectively by the biosorption equilibrium with Langmuir adsorption isotherm. According to the whole data analysis in each experiment of studying Cu2+ and Pb2+ biosorption including condition factors and adsorption isotherm, the adsorbed capacity of Pb2+ by A. polytricha biomass was bigger than Cu2+. The biosorption by A. polytricha was most effective when pH 5–6. The biosorbents are suitable for low Cu2+ and Pb2+ concentration waste-water, especially for Pb2+ removal.
