Effluents containing heavy metals can be remediated with the help of dead microorganisms by the process known as biosorption. In this study the dead biomass 1of fungus Aspergillus flavus was used for the biosorption of heavy metals i.e., Zinc and Nickel. The capacity of biosorption by the dead biomass of Aspergillus flavus was evaluated at room temperature with different parameters which are; pH, contact time, biomass concentration and metal ion concentration. The biosorption capacity for Zn was found to be 47.36% at room temperature, at pH 6.5, with biomass concentration of 2g/L having contact time of 50 min and solution concentration of 2ppm. Biosorption capacity for Ni was found to be 61.60% at room temperature, at pH 5, with biomass concentration of 2g/L having contact time of 60 min and solution concentration of 2ppm. . In this study, desorption of the heavy metals by 0.1M HCl was found to be effective. Fungal biomass was recovered for reuse.
