摘要
采用离心脱水、取样器取样、混合酸分解、亚铁还原－钒酸铵容量法测定树脂中的铀。方法简便、快速，精密度≤±５％，回收率达９８％－１００％．１．５ｈ可测定１０个树脂样。
simple and rapid volumetrical method for determination of the uranium in the ion-exchange resin was proposed. The uranium was determined by volumetry.using ammonium vanadate after centrifugal dewatering of the resin, sampling with a specially-disigned sampler, decomposition with H2SO4,HNO, and HClO4, and reduction with Fe2+. The precision of the method was ≤±5%, and the recovery reached 98%-100%. 10 resin samples could be analysed within 1. 5h.
