英文摘要 | The biosorption of Cd(2+) and Pb(2+) by fruiting body wastes of macrofungi Flammulina velutipes was studied. The factors affecting absorbtion including pH, initial metal concentration, biosorbent dosages and mutual competitive biosorption of both metal ions were focused. The sorption of Cd(2+) and Pb(2+) was increased with pH value from 2 to 6 and maximum biosorption was at pH 6. The quantity of Cd(2+) and Pb(2+) adsorbed increased with the initial concentration of metal ions and both metals removal gradually increased with the biosorbent dosage. There existed mutual competitive biosorption between Cd(2+) and Pb(2+) 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 Cd(2+) and Pb(2+) by F. velutipes was 8.4317 mg/g dry biomass with R(2) of 0.9228 and 18.3486 mg/g dry biomass with R(2) of 0.9280, respectively. Pseudo-first order equation fitted for adsorption data of Cd(2+) with R(2) of 0.9504, while pseudo-second order equation more fitted for adsorption data of Pb(2+) with R(2) of 0.9917. |
