摘要：

Biosorption of chromium from effluent generated in chrome-electroplating unit using waste yeast biomass Saccharomyces cerevisiae was carried out. Chromium concentration in the effluent was 204 mg/L. Chromium biosorption equilibration time was found to be 2 hours, with uptake of 6.607 mg/g. Biosorption increased with rise in pH and chromium concentration. Equilibrium biomass concentration and agitation speed were 2% and 150 rpm, respectively. The biosorption equilibrium data fit with Freundlich and Langmuir isotherm models revealed K-f and Q(max) values of 0.3727 and 384.61 mg/g, respectively.
