| 3 | Biosorption of lead by Phanerochaete chrysosporium in the form of pellets显示文摘The growth of Phanerochaete chrysosporium (ATCC 24725) in pellets was influenced by culture time, medium pH, C/N, surfactant concentration, spore number in inoculum, and shaking rate. The removal of Pb 2+ from aqueous solution by this kind of mycelial pellets was studied. The results indicated that many factors affected biosorption. These factors included pH, Pb 2+ concentration, co ion, adsorption time, and chemical pretreatments of biomass. Under optimum biosorption conditions(pH 4 5, 27℃, 16h), the highest lead uptake of 108 mg/g, was observed with mycelial pellets of 1 5-1 7 mm in diameter which were treated with 0 1 mol/L NaOH solution before adsorption. Pretreatment of biomass with NaOH further increased its biosorption capacity. | WuJ LiQB | 2002 | Journal of Environmental Sciences2002，14，1： | 0 |
