研究了Pr(Ⅳ)、Tb(Ⅳ)高碘酸根配合物的L→M电荷迁移跃迁,利用紫外-可见分光光度计探讨了配合物阴离子在KOH水溶液中自还原反应的动力学规律,测出了电子转移反应过程的动力学参数。根据实验现象及测定结果推出了Ln(Ⅳ)IO_6~-配离子在水溶液中自还原反应的机理,并对其进行了验证。
The transition of L → M charge of Pr (Ⅳ) and Tb (Ⅳ) periodate complexes was studied. The kinetics of self-reduction of complex anions in KOH aqueous solution was investigated by ultraviolet-visible spectrophotometer. The kinetic parameters of the electron transfer reaction process. The mechanism of self - reduction reaction of Ln (Ⅳ) IO_6 ~ - ions in aqueous solution was introduced according to the experimental phenomena and the determination results.
