用N1923-二甲苯作固定相,AD201大孔聚二乙烯苯吸附树脂作裁体,研究了钍在硫酸介质中的反相分配色层分离条件。拟定了矿石中微量钍的测定方法。
Using N1923-xylene as the stationary phase and AD201 macroporous poly (divinylbenzene) adsorbent as the host, the separation conditions of reversed-phase partitioning of thorium in sulfuric acid were studied. A method for the determination of trace amounts of thorium in ores has been developed.
