摘要
This study presents removal of chromium (III) from aqueous solution by microbial waste biomass (MB2) obtained as a byproduct of pharmaceutical fermentation industry, Sorption kinetic behavior of Cr(III) was studied in a series of experiments in batch mode at different pH, adsorbent dosage and initial Cr concentration. Optimum Cr(III) removal (73.9%) from aqueous Solution was at pH 4 by 1% biomass dosage. A comparison of kinetic models (Lagergren, Ho & McKay, Elovich & Morris-Weber) and correlation coefficient (R-2) indicated that Ho & McKay kinetic model correlates well with experimental kinetic data.
