Özet
In this study, the adsorption conditions of Fe2+ ions on Saccharomyces cerevisae immobilized pumice stone were investigated by column method. In order to perform this aim, the effect of solution pH value, initial concentration of ions and suitable solution and concentration for recovery of adsorbed ions were investigated. At pH 5, the maximum adsorption was obtained. At optimal pH value, adsorption capacity of sorbent for metal was obtained as 1,81 mg.g(-1), when initial concentration was 60 mg.ml(-1). Influence of HCl, NaCl, NH4Cl and EDTA solutions on desorption were investigated and maximum recovery was achieved by 0,2M EDTA solution. Desorption were 98% level provided by 0,2 M EDTA solution.
