The use of Phanerochaete chrysosporium for modification of bentonite for preconcentration and determination of heavy metals

Abstract In this study, a solid phase extraction method was successfully applied in the preconcentration and determination of trace levels Cu(II) Cd(II) ions Phanerochaete chrysosporium (white rot fungus) modified bentonite used as adsorbent. After biosorption ions, metal concentrations samples were determined by atomic absorption spectrophotometry. pH, adsorbent amount, eluent type, sample volume, flow rate, which are effective adsorption have been studied. 1 M HCl for desorption these retained (recovery 95–100%). addition, effect interfered has also investigated. Sorption data examined according to Langmuir Freundlich equations. The results obtained show that high capacity, recovered. It successful applying proposed enrichment real water samples. Recovery values between 92.3% 97.3% studied ions. According results, can be analysis at 95% confidence interval.
