The Removal of Cd and Cu from Aqueous Solution Using Sorbents Siirt Peanut Shells Immobilized on Amberlite XAD-4

Abstract

In this study, sorbents as Siirt peanut shell with Amberlite XAD-4 immobilized on
polymers of Cd (II) and Cu(II) ions were investigated conditions of enrichment by solid
phase extraction method. The effect of the recovery yield of the ambient pH, eluent
type and concentration, solution flow rate, the effect of solution volume, salt effect,
column repeatability, examined the application of certified reference material and
environmental samples. Improved method has provided 60 times enrichment for Cu
and Cd. Under optimum conditions, Cu and Cd recovery yields were found to be Cu
98.43 ± 3.76 and Cd 98.76 ± 4.11 for the 95% confidence level. Besides, the relative
standard deviation of Cu and Cd were determined to be 6.51 and 7.11 % for 3 repeat
experiments.
