英文摘要 | The biosorption of Cd2+ and Pb2+ by fruiting body wastes of macro-fungi Flammulina velutipes was studied. The factors affecting absorption including pH initial metal concentration, biosorbent dosages and mutual competitive biosorption of both metal ions were focused. The sorption of Cd2+ and Pb2+ was increased with pH value from 2-6 and maximum biosorption was at pH6. The quantity of Cd2+ and Pb2+ adsorbed increased with the initial concentration metal ions and both metal removal gradually increased with biosorbent dosage. There existed mutual competitive biosorption between Cd2+ and Pb2+ when they were in the same solution. The Langmuir isotherm model fitted both metal ions sorption data well in the experiment and the calculated maximum sorption capacity of Cd2+ and Pb2+ by F. velutipes was 6.84 mg.g(-1)dry biomass with R-2 of 0.9775 and 13.61 mg.g(-1)dry biomass with R-2 of 0.9661, respectively. Pseudo-first order equation fitted for adsorption data of Cd2+ with R-2 of 0.9504, while pseudo-second order equation more fitted for adsorption data of Pb2+ with R-2 of 0.9917. |
