Abstract

In solutions with рН 1.5–2.0, terbium(IV) stabilized with phosphotungstate anions P₂W₁₇O₆₁^10– in the presence of a slight excess of the unsaturated phosphotungstate slowly oxidizes plutonium(VI). The arising Pu(VII) cation forms a complex with unsaturated phosphotungstate anions and is rapidly reduced with water. Flash radiolysis may be an efficient tool for studying the Pu(VI) oxidation, e.g., with the OH^· radical and the reaction of Pu(VII) with water.

不饱和磷钨酸盐K10P2W17O61酸性溶液中Tb（IV）对Pu（VI）的作用

在рН 1.5-2.0的溶液中，用磷钨酸盐阴离子P2W17O6110 -稳定的铽（IV）在少量过量的不饱和磷钨酸盐存在下缓慢氧化钚（VI）。产生的Pu（VII）阳离子与不饱和磷钨酸盐阴离子形成络合物，并与水迅速还原。闪蒸辐射解可能是研究Pu（VI）氧化的有效工具，例如与OH·自由基的氧化和Pu（VII）与水的反应。
