本文用电位法研究Eu~(3+)、Gd~(3+)的水解聚合作用.采用两种方法确定水解产物的组成及其平衡常数.实验结果表明,Eu~(3+)和Gd~(3+)在溶液中的状态与Sm~(3+)相同.
In this paper, the electropolymerization of Eu ~ (3 +) and Gd ~ (3+) was investigated by potentiometric method.The composition and the equilibrium constant of the hydrolyzate were determined by two methods.The experimental results showed that Eu ~ (3+) and Gd ~ (3+) in solution is the same as Sm ~ (3+).
