Crown 합성수지를 이용한 금속 이온들의 특성에 관한 연구
A Study on the Characteristic of Metal Ions Utilizing Crown Synthetic Resin
The new ion exchange resin was synthesized from chloromethylated styrene-1,4-divinylbenzene with crown macrocyclic ligand by substitution reaction. The resin was prepared and the effect of pH, time, dielectric constant of solvent and cross-linked of the matrix on the adsorption for UO2(2+), Co(2+) and Nd(3+) was investigated. The metal ion was not adsorbed on the resins pH range below 3 and above pH 4 fast adsorption behavior was showed. The resin selectivity determined in ethanol matrix was increasing order UO2(2+) > Co(2+) > Nd(3+). In addition, these metal ion was separated on the column packed with 1% crosslinked resin as an eluent.
