已知铀(VI)的催化还原波有两个,卽V(IV)对于UO_2~(++)离子第一个还原波的催化作用,以及NO_3~-离子对UO_2~(++)离子第二个还原波的催化作用。郑淑蕙等在研究V(IV)对于UO_2~(++)离子第一个还原波的催化作用时观察到:当阴离子与铀(VI)有较强的络合作用时,随着阴离子浓度的增加,催化电流逐渐减少,但对UO_2~(++)离子第二个催化还原波的类似观察,迄今似还未曾有人系统作过。我们研究了氯离子对UO_2~(++)离子第二个催化还原波的影响,发现随着氯离子浓度
It is known that there are two catalytic reduction waves for uranium (VI), the catalytic effect of 卽V (IV) on the first reduction wave of UO_2 ~ (++) ions, and the effect of NO_3 ~ - on UO_2 ~ (++) Two reduction wave catalytic. Zheng Shuhui et al. Studied the catalytic effect of V (IV) on the first reduction wave of UO_2 ~ (++) ions: when the anions and uranium (VI) have strong complexation, with the increase of anion concentration , The catalytic current decreases gradually, but a similar observation of the second catalytic reduction wave of UO_2 ~ (++) ion has not been done before. We studied the effect of chloride ion on the second catalytic reduction of UO_2 ~ (++) ions. It was found that with the chloride ion concentration
