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.eninfo:eu-repo/semantics/openAccessAmberlite XAD-4solid phase extractiontrace elementCuCdArticle131N/AWOS:000429190200002N/A2-s2.0-8504066456210.12973/ejac/78720
