本文提出用国产多孔743阳离子树脂分离矿石中的锆、稀土及钍。所拟定的分析程序可用于测定矿石中0.00x～x%的锆、稀土和钍。由于该树脂孔径大、交换速度快,容易洗涤,因而只须用少量溶液即可洗涤杂质、洗脱待测元素及再生树脂,提高了分析速度,克服了732、Zerolite 225等阳离子树脂难于洗提的缺点.本法操作简易,结果较稳定.试剂和仪器树脂及玻璃交换柱:743树脂(浙江余杭争光塑料
This paper proposes the separation of zirconium, rare earth and thorium in ore by using domestic porous 743 cationic resin. The proposed analytical procedure can be used to determine zirconium, rare earth and thorium in the ore at levels of 0.00x to x%. As the resin pore size, exchange speed, easy to wash, so just a small amount of solution can be washed impurities, elution of test elements and resin regeneration, to improve the analysis speed, to overcome the 732, Zerolite 225 and other cationic resin difficult to elute The method is simple, the result is more stable.
