| 英文摘要 | Use polyvinyl alcohol-Na-alginate (PVA-SA) to immobilize Lentinus edodes residue for Cd(2+) removal. In a single-metal solution, the biosorption of Cd(2+) reached equilibrium within 7 h which can be well described by a pseudo-second-order model, with equilibrium biosorption 0.2008 mg/g; 4-7 was the suitable pH value for Cd(2+) biosorption by immobilized fungus, a much wider range than that required by mobilized fungus. Unlike the single-metal solution, the Cd(2+) biosorption ratio in a two-metal solution increased linearly as the pH values increased. When the concentration of the interferential ion (Cu(2+)/Pb(2+)) increased, Cd(2+) biosorption decreased significantly (p = 0.01). Isotherm analysis showed that Cd(2+) biosorption increased as the initial concentration in a single-metal solution increased. When the initial Cd(2+) concentration in the two-metal solution increased, the biosorption increased at first, but when the Cd(2+) concentration was over 90 mg/g, a remarkable decrease occurred. Langmuir, Freundlich, Dubinin-Radushkevich and Langmuir-Freundlich isotherm models were fit to the experimental data. The Langmuir model fit the Cd(2+) isotherm biosorption best, with correlation coefficients of 0.9981 in Cd(2+) single-metal Solution and 0.9291 in a Cd(2+)-Pb(2+) solution. The D-R isotherm fit the Cd(2+) isotherm biosorption in the Cd(2+)-Cu(2+) solution with a correlation coefficient of 0.9623. |
