The Removal of Cd from Aqueous Solution Using Sorbents Almont Shell Immobilized On Amberlite XAD-4

In this study, sorbents as almont shell with Amberlite XAD-4 immobilized on polymers of Cd (II) ion was 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 10 times enrichment for Cd. Under optimum conditions, Cd recovery yield was found to be 98.50 ± 3.89% for the 95% confidence level. Besides, the relative standard deviation of Cd was found to be 3.21% for 3 repeat experiments.
