Sorption study of Cadmium(II) in glycine medium using poly [dibenzo-18 crown-6] and Column chromatography

Author(s): ND Nikam, PS Patil, BS Mohite
Abstract: A simple chromatographic separation method has been developed for quantitative sorption of Cadmium(II) from an aqueous solution of 1×10-3 M Glycine using poly [dibenzo-18-crown-6] as stationary phase. The sorption of Cadmium(II) was quantitative 1×10-2M to 1×10-4M Glycine. The elution of Cadmium(II) was quantitative with 1.0–8.0 M HCl, 1.0-8.0M HClO4, 2.0-8.0 M H2SO4 and 1.0-8.0M CH3COOH The capacity of poly [dibenzo-18-crown-6] for Cadmium(II) was found to be 0.533 ± 0.01 mmol/g of crown polymer. The effects of concentrations of Glycine, Cadmium(II), foreign ions and eluents have been studied. Cadmium(II) was separated from a number of cations in multicomponent mixtures. The applicability of the proposed method was ascertained for the determination of Cadmium(II) in real samples. The reliability of method was checked by comparison of the results with those obtained using flame photometer. The method is very simple, rapid and selective with good reproducibility (approximately±2%).
