The removal of hexavalent chromium from aqueous solution was carried out in batch experiments using fungal biomass of Aspergillus niger. All the fungal biomass completely removed chromium (VI) from aqueous solutions. Chromium (VI) was removed from aqueous solutions by the reduction to chromium (III) when it contacted with the biomass. The removal rate of chromium (VI) increased with a decrease in pH or with increase of chromium (VI) was proportional to total chromate concentration, and equivalent concentration of organic compounds.

Abstract


The removal of hexavalent chromium from aqueous solution was carried out in batch experiments using fungal biomass of Aspergillus niger. All the fungal biomass completely removed chromium (VI) from aqueous solutions. Chromium (VI) was removed from aqueous solutions by the reduction to chromium (III) when it contacted with the biomass. The removal rate of chromium (VI) increased with a decrease in pH or with increase of chromium (VI) was proportional to total chromate concentration, and equivalent concentration of organic compounds.
