Heavy Metals Biosorption by Powdered Rhizopus Oligosporus Biomass

The biosorption of several metals by powdered biomass of Rhizopus oligosporus was investigated. Cells of Rhizopus olzgosporus were cultured, harvested, washed, oven dried and mixed in solutions containing lead, copper, cadmium and aluminium ions. After an equilibration period, the biomass was se...
