Biosorption of chromium (VI) and calculations of Langmuir's and Freundlichs isotherms

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. Langmuir's and Freundlichs isotherms were also plotted to observe the maximum biosorption of heavy metal chromium (VI). (author)
