Biosorption of Chromium (VI) and Calculations of Langmuirs and Freundlichs Isotherms

Biosorption of Cr(VI) by Yeast Biomass

Abstract

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