| 英文摘要 | To investigate the potential use of Lentinus edodes (L. edodes) residue for Cd2+ adsorption, poly alcohol Na alginate (PVA) was applied to immobilize it. The parameters including contact time, pH, adsorbent dosages, and coexisting metal ions were studied. The suitable pH for immobilized L. edodes was 4-7 wider than that for raw L. edodes (pH 6-7). In the presence of Pb2+ concentration varying from 0 to 30 mg center dot L-1, the Cd2+ adsorption ratios declined by 6.71% and 47.45% for immobilized and raw L. edodes, respectively. While, with the coexisting ion Cu2+ concentration varied from 0 to 30 mg center dot L-1, the Cd2+ adsorption ratios declined by 12.97% and 50.56% for immobilized and raw L. edodes, respectively. The Cd2+ adsorption isotherms in single-metal and dual-metal solutions were analyzed by using Langmuir, Freundlich, and Dubinin-Radushkevich models. The Cd2+ adsorption capacities (q (m)) in single-metal solution were 6.448 mg center dot L-1 and 2.832 mg center dot L-1 for immobilized and raw L. edodes, respectively. The q (m) of immobilized L. edodes were 1.850 mg Cd center dot g(-1) in Cd2+ + Pb2+ solution and 3.961 mg Cd center dot g(-1) in Cd2+ + Cu2+ solution, respectively. The Cd2+ adsorption processes subjected to both adsorbents follow pseudo-second-order model. Mechanism study showed the functional group of L. edodes was -OH, -NH, -CO, and PVA played an important role in metal adsorbing. Mining wastewater treatment test showed that PVA-SA-immobilized L. edodes was effective in mixed pollutant treatment even for wastewater containing metal ions in very low concentration. |
