| Abstract: | The effect of initial pH on biosorption by Saccharomyces cerevisiae of total chromium present in tannery effluent was investigated. Maximum biosorption efficiency was evident at neutral pH with a metal removal efficiency of 99 %. S. cerevisiae was then pretreated with NaOH and HCHO-HCOOH to study the role of proteins and amino acids, respectively, in biosorption. At pH 7, 9 and 11, biomass pretreated with NaOH exhibited significant biosorption as compared to raw biomass and that treated with HCHO-HCOOH. However, trend reversed at pH 2. At pH 4, untreated biomass exhibited maximum chromium sorption, when compared to that treated with NaOH and HCHO-HCOOH. |
