U(Ⅵ),Th(Ⅳ)与邻香草醛缩对苯二胺配合物的合成与表征

SYNTHESIS AND CHARACTERIZATION OF U(Ⅵ) AND Th(Ⅳ) COMPLEXES WITH o-VANILLIN-p-PHENYLENEDIAMINE

合成了硝酸铀酰、硝酸钍与双希夫碱邻香草醛缩对苯二胺 (以L表示 )的 2种固体配合物。通过元素分析、红外光谱、紫外光谱、差热 热重及摩尔电导分析等方法 ,确定配合物的组成分别为[UO2 LNO3]NO3,[ThL(NO3) 2 ](NO3) 2 。

Two new solid complexes of uranyl nitrate and thorium nitrate with bis Shiff base o vanillin p phenylenediamine (L) have been synthesized and characterized by elemental analysis, IR, UV, DTA TG and molar conductance. The compositions of the complexes are confirmed to be [UO 2LNO 3]NO 3 and [ThL(NO 3) 2](NO 3) 2. Some properties of the complexes are studied.
