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

摘要: 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 LNO3NO3,ThL(NO3) 2 (NO3) 2 。对它们的配位方式和某些物理化学性质进行了研究

Abstract: 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 3NO 3 and ThL(NO 3) 2(NO 3) 2. Some properties of the complexes are studied.
