摘要
采用717阴离子交换树脂分离钍与钆及其他元素,超声波雾化,高频电感耦合等离子体原子发射光谱法测定分离液中微量钍。取样1.0g时,测定下限为0.20μg·g-1,方法回收率为99.2%,相对标准偏差RSD为11.7%(n=6)。
The thorium was separated from Gd2O3 by 717 anion exchange resin,determined by inductively coupled plasma atomic emission spectrometry with ultra sonic nebulization. When the weight of sample is 1.0g, the detection limit of method is 0. 2μg·g^-1 with the recovery of 99. 2% and standard deviation of 11.7%.
