摘要
A new adsorbent QCR was prepared with quinine impregnated on cation exchange resin. It was found that QCR was stable in the solution of HCl(0.1～3.0 mol/L). Separation and preconcentration of noble metal ions (Au、Pd、Pt) by QCR have been studied by Inductively Coupled Plasma Atomic Emission Spectronetry (ICP\|AES). More than 93% of noble metal ions were adsorbed by QCR in 0.1mol/L HCl; and the analyte could be eluted quantatively by using 2 g/L thiourea -0.1 mol/L HCl as the eluant. The adsorption selectivity to Au、Pd、Pt is good at the existence of some non\|noble ions. This method has been applied to the analysis of catalysts and anticancer drugs with satisfactory results.\;
