Biosorption of Chromium (VI) and Calculations of Langmuir’s and Freundlichs Isotherms

Abstract

In the present study yeast biomass has been successfully used as biosorbent for removal of Crfrom aqueous solution. Yeasts of Saccharomyces cerevisiae are effective biosorbents for heavy metal ionsand it can be bought in large quantity at low cost. S. cerevisiae can remove toxic metals from aqueoussolutions to various levels. This low-cost biosorbent will make the process cost-effective and competitiveparticularly for environmental applications in detoxifying effluents. Langmuir’s and Freundlichs isothermswere also plotted to observe the maximum biosorption of heavy metal chromium (VI).
