Abstract

Cerium(IV) hydrolysis in sulfate solutions is studied spectrophoto- and photometrically, pH-metrically and potentiometrically at the ionic strength I = 2 in the pH range 0.2–3.0 at 294.95 K. The equilibrium constants of hydrolysis of cerium(IV) sulfate complexes are calculated; the yield diagram of cerium(IV) hydrolytic species occurring in sulfate solutions is plotted. The stability constants of binuclear cerium(IV) hydroxo complexes with dioxysuccinic (tartaric) carboxylic acid are calculated in terms of the advanced hydrolysis model.

摘要

在 294.95 K 时，在 0.2-3.0 的 pH 值范围内，离子强度I = 2 下，用分光光度法和光度法、pH 法和电位法研究了硫酸溶液中的铈 (IV) 水解。硫酸铈 (IV) 配合物水解的平衡常数被计算；绘制了硫酸盐溶液中铈 (IV) 水解物种的产率图。根据先进的水解模型计算了双核铈（IV）羟基配合物与二氧琥珀酸（酒石酸）羧酸的稳定性常数。
