摘要：
<正>Magnetic polythioether chelating resin （PSE2） was pre-pared. Its average diameter was 0. 25mm and it contained magnetic parti-cles over 22% of the microcapsules afer it had been treated with 2N hotHCl, and it would be destroyed in 5N hot HCl. The results showed thatreaction medium had remarkable effect on physical farms of the microcap-sules. PSE2 had very high adsorption capacity to Au3+ and Hg3+, andlittle one towards Mg3+, Pb2+. It was discovered that PSE2 could reduceAu3+ into elemental gold and Pt4+ to Pb2+.
