本文对控制电位电解法制备U~(3+)过程中影响还原率和还原速度的各种因素进行了探讨并认为电解池常数β是主要因素,β越大,还原率和还原速度越高。还用控制电位电解法研究了H~+和U~(3+)反应的动力学。实验表明,该反应是一个二级反应,可以表示为: In this paper, various factors influencing the reduction rate and the reduction rate during the preparation of U ~ (3+) were investigated. It was considered that the cell constant β was the main factor. The larger β was, the higher the reduction rate and the reduction rate were. The kinetics of H ~ + and U ~ (3+) reactions were also studied by controlled potential electrolysis. Experiments show that the reaction is a secondary reaction, which can be expressed as:
