Surfactant Assistant Enhancement of Bioremediation Rate for Hexavalent Chromium by Water Algae

Rumki Nandi, Kakali Mukherjee and Bidyut Saha

Cr(VI) in waste water is a serious pollutant in diverse environmental conditions due to its toxicity and carcinogenicity. Bioremediation can alternatively be used to the conventional chemical treatments. Bioremediation of toxic hexavalent chromium is done by reduction of hexavalent chromium to nontoxic trivalent chromium in consequence of oxidation of organic components present in the water extract of water algae. The rate of bioremediation is increased by anionic surfactant sodium dodecylsulphate (SDS) and neutral surfactant Triton-X-100 (TX-100). In the present study micellar catalysts are used as surfactans. SDS is found to be most suitable among the catalyst. All the observations were recorded using UV-Vis, fluorescenece and FTIR spectrophotometer.
