Comparative study for the separation, preconcentration, and determination of copper and cadmium in real samples by using two different ligands
The metal complexes are retained on resin at pH 6.0 and eluted with 1.0 mol L −1 HCl in acetone in both methods. After the optimum conditions were determined, the methods were applied to seawater, stream water, rice, lentil, tea, tobacco, bulgur, chickpea, wheat, red pepper, black pepper, peppermint, and dried eggplant samples in order to determine the levels of copper and cadmium.
