本文提出用具有基团为■的螯合树脂(3926-Ⅱ号)以一步分组分离的放化中子活化分析法测定阳极泥中金、银、铱,结合高分辨率Ge(Li)谱仪对树脂进行直接测定。该树脂能选择性定量吸附贵金属元素,用放射性示踪法测定Au、Ag、Ir放化分离的回收率分别为98.3,98.5,97.7%,方法对阳极泥中Au、Ag、Ir含量进行了测定。方法可靠性用低品位贵金属矿样核对,结果相符。 This paper presents the determination of gold, silver and iridium in anode slime by radiochemical neutron activation analysis with a chelating resin (3926-Ⅱ) The resin is measured directly. The resin can selectively and quantitatively adsorb precious metal elements. The recoveries of Au, Ag and Ir determined by radioactive tracing method were 98.3, 98.5 and 97.7% respectively. The contents of Au, Ag and Ir in anode slime were determined . Method reliability with low-grade precious metal ore sample check, the result is consistent.
