Volume 9, Issue 3
Abstract
Batch biosorption of chromium(VI) from an aqueous solution was studied using dry biomass of Fusarium sp. isolated from soil. At the initial metal ion concentration of and pH 2.0, the Cr(VI) adsorbed was of adsorbent. The Cr(VI) adsorbed increased with increasing initial metal ion concentration up to . A maximum removal of was observed at pH 2.0 at initial Cr(VI) concentration. An increase in pH from 2 to 6 decreased Cr(VI) removal from at metal ion concentration. At all the concentrations, the adsorption equilibrium was obtained within . The adsorption equilibrium constants were obtained from both Freundlich and Langmuir adsorption isotherms. The organism was also found to remove of Cr(VI) per gram of adsorbent from an effluent generated from an electroplating industry.
