简要总结了 Se(IV) 的溶液化学，特别是酸碱性质、盐和络合物的形成、化学还原以及 Se(IV) 与有机和无机硫化合物的反应。详细讨论了 Se(IV) 在滴落和固定汞电极上的电化学还原。讨论了先前酸碱平衡和还原产物 Se2− 的连续反应的影响、其产物的吸附以及添加的金属离子的影响。总结了溶出分析法测定超痕量Se(IV)的原理和应用。比较了非反应性（Au、Pt、碳）和反应性（Hg、Ag、Cu）电极上的行为。
Solution chemistry of Se(IV), in particular the acid–base properties, salt and complex formation, chemical reduction and reaction of Se(IV) with organic and inorganic sulfur compounds are briefly summarized. The electrochemical reduction of Se(IV) on dropping and stationary mercury electrodes is dealt with in some detail. The effects of antecedent acid–base equilibria and of consecutive reactions of the reduction product, Se2−, adsorption of their products, and effects of added metal ions are discussed. The principles and applications of stripping analyses for determination of ultratraces of Se(IV) are summarized. The behavior on unreactive (Au, Pt, carbon) and reactive (Hg, Ag, Cu) electrodes are compared.
