摘要: Bioleaching process, which causes acidification and solubilization of heavy metals, is one the promising methods for removing metals from contaminated sediments. The sediments governed by sediment pH. In present study, significance pH in bioleaching was evaluated at different solid contents a bench-scale reactor. Results showed that temporal change process effected buffering capacity particulates. variations this were calculated modified logistic model. It observed highly pH-dependent. addition, non-linear equation metal relating value established. This allows an easier faster estimate measuring process.
