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 Au~(3+) and Hg~(3+), andlittle one towards Mg~(3+), Pb~(2+). It was discovered that PSE2 could reduceAu~(3+) into elemental gold and Pt~(4+) to Pb~(2+). Its average diameter was 0.25 mm and it contains magnetic parti- cles over 22% of the microcapsules afer it had been treated with 2N hot HCl, and it would be destroyed in 5N hot HCl . The results showed that the reaction medium had remarkable effect on physical farms of the microcap-sules. PSE2 had very high adsorption capacity to Au ~ (3+) and Hg ~ (3+), and little one towards Mg ~ (3+), Pb ~ (2+). It was discovered that PSE2 could reduceAu ~ (3+) into elemental gold and Pt ~ (4+) to Pb ~ (2+).
