摘要: 我们曾用D290大孔强碱性阴离子树脂与偶氮氯膦Ⅲ(CPA-Ⅲ)水溶液,经搅拌制得偶氮氯膦Ⅲ螯合形成树脂,以分离富集岩石中微量稀土元素,再用ICP光电直读光谱法测15种稀土元素的分量[2],结果满意,本文研究了CAP-Ⅲ螯合形成树脂的基本特性。

Abstract: This paper reports the preparation of the CPA-Ⅲ Chelate-forming resin, its analytical performance towards rare-earth elements, such as the effect of pHon the adsorption of CPA-Ⅲ onto D290 resin, the exchange capacity of D290 resin, the adsorption capacity of CPA-Ⅲ chelate-forming resin for Ce, the stability of CPA-Ⅲ resin in different mediums etc, and the law of synthesizing well-behaved chelateforming resin.
