采用对六价锕系元素含氧离子(MO_2~(2+))具有选择性响应的离子选择电极,电位法测定了MO_2Ac~+(M——U,Np,Pu;Ac——醋酸根离子)络离子稳定常数和几种有机化合物还原Np(Ⅵ)的反应速度常数并与采用其它方法获得的数据进行了比较。还探讨了这种离于选择电极用于锕系元素络合过程热力学和氧化还原过程动力学研究的可行性。
The ion - selective electrode with selective reaction to hexavalent actinide - containing oxygen ions (MO_2 ~ (2+)) was used to measure the content of MO_2Ac ~ + (M - U, Np, Pu; Ac-- ) Complex ion stability constants and the reaction rate constants of several organic compounds to reduce Np (Ⅵ) were compared with those obtained by other methods. The feasibility of this kinetic study of thermodynamics and redox processes for the actinide complexation process at the selective electrode was also discussed.
