Abstract: Nowadays biosorption technology is primarily used as a potent tool for solving the environmental pollution, as compared to conventional methods because of its low cost, and environmental safety. It is not associated with secondary pollutions during its operation. The present study is based on checking the capacity of live and pretreated biomass of Aspergillus species for the biosorption of lead metal ions. Among the five species tested, the best results were obtained for A. niger. While the minimum and maximum removals of lead metal ion by live A. niger biomass were 3.84 and 16.42 mg/g at 2 mM and 9 mM concentration respectively, it was increased to 31.25 and 48.44 mg/g respectively at same base concentration for pretreated biomass. Overall, it was observed that pretreated alkali biomass of test fungal species is a potent biosorbent for the metal ions.
