摘要
本文合成了TOPO—TBP—萃淋树脂,报道了此树脂在硝酸及盐酸中萃取钍、铀的分配比及适于分离的条件,提出了分离钍、铀的色谱法,并用于合成溶液及矿石样品中钍和铀的测定。
A sythetic method is described for the preparation of TOPO—TBP—containing resin.Distribution ratios are reported for Th and U between this resin and solutions of hydrochloric acid and nitric acid.Some factors effect separation are discussed.Based on this,a chromatographic method is proposed for separation of Th and U.The method has been applied to determining Th and U in artificial solutions and ore sample.
