Abstract

The preparation and spectrophotometric properties of a new type of complex compound of arsenazo I with Pu(IV) in the presence of H(2)O(2) are described. The new compound has a blue colour, derived from a wide absorption band with a maximum at 610 nm. and a corresponding molar absorptivity of 4 x 10(4) l. mole(-1).cm(-1). From 2 hr after its preparation this curious new compound undergoes for several days a steady decomposition accompanied by decolorization. The formation of similar peroxy Pu(IV) complexes has not so far been shown to take place with arsenazo III or with any other "arsenazo-type" reagent.

摘要

本文描述了在 H2O2 存在下，新型 Pu(IV) 偶氮 I 络合物的制备及分光光度性质。新化合物呈蓝色，源于宽吸收带，最大吸收波长在 610nm，相应的摩尔吸光系数为 4 x 10(4) l. mole(-1).cm(-1)。从制备后 2 小时开始，这种奇特的新化合物会在数天内稳定分解并伴随着褪色。到目前为止，尚未发现类似的过氧 Pu(IV) 络合物与偶氮 III 或任何其他“偶氮型”试剂形成。
