Abstract
The metal uptake capacity of a bacterial strain (namely W-6) isolated from both activated sludge and heavy metals contaminated soil adjacent to an electroplating plant was investigated. Being acclimated by high metal concentration solution, the biosorption rate and zinc tolerance of W-6 were significantly improved. The optimal parameters for W-6 were pH at 6.0, temperature at 40℃, 8 hours' sorption time, 100 mg•L-1 of zinc concentration, biomass of 3 g•L-1 with 3 days' culturing, and wherein 27.63 mg•L-1's zinc removal with corresponding sorption rate of 81.68% could be reached. The absorption models matched both Langmuir and Freundlich Isotherm Adsorption Equation. This research provided the basis of applying biosorption in treating heavy metals of sewage treatment plant sludge.
