用螯合树脂对金属进行分离富集及测定，前人已做了许多有意义的研究［１～４］．曾用含键合Ｓ双硫腙（Ｐ－Ｄ）和脱氢双硫腙（Ｐ－ＤＴ）功能团的离子交换树脂和螯合树脂分离金和铂族金属［５］，用双硫腙负载树脂分离富集Ｃｕ（Ⅱ）［６］，用磺基二硫腙负载树脂分离富集...
Separation and enrichment of metals with chelating resins and determination of the predecessor has done a lot of meaningful research [1 ~ 4]. Gold and platinum group metals have been separated with ion exchange resins and chelating resins containing functional groups bonded to dithianhydrazone (P-D) and dehydrodithione (P-DT) [5], supported with dithizone Resin separation and enrichment of Cu (Ⅱ) [6], with sulfo-dithizone loaded resin separation and enrichment ...
