摘要
对249Cf、Sm和Gd的水溶液(10−4−10−3 M)进行了直流极谱和循环伏安研究。从目前的数据和Sm和Gd的电化学行为可以推断，Cf(III)在汞滴电极上被还原为两个步骤，首先是Cf(II)，然后Cf(II)被还原为Cf(Hg)。这两个电化学步骤的电位分别为- 1.47和- 1.68V vs NHE。
Electrochemical studies of trivalent californium and selected trivalent lanthanides in aqueous solution
D.c. polarographic and cyclic voltammetric studies have been carried out on aqueous solutions (10−4−10−3 M) of 249Cf, Sm and Gd. From the present data and the established electrochemical behavior of Sm and Gd, it can be inferred that Cf(III) is reduced in two steps at the mercury-drop electrode, first to Cf(II), followed by the Cf(II) being reduced to Cf(Hg). The potentials for the two electrochemical steps are −1.47 and −1.68V vs NHE, respectively.
