摘　　要：本文研究了重稀土元素（钇组）形成四元络合物的最佳条件、络合物的组成及其极谱吸附催化波的性质和络合物稳定常数的测定，结合萃取色层分离方法测定了稀土矿石、土壤中的重稀土元素钇，获得满意的结果。The paper studys optimal conditions for determination of heavy rare earthy elements by forming tetrabasic complex, and composition of the conmplex. Furthermore, the characteristics of its polarographic adsorption catalytic wave and mechanism of electrode reaction have been investigated. With chromatographic seperation by extraction column. The system has been successfully applied to determine heavy rare earth element yttrium in ores and soil with satisfactory results.
