铀-2,5-吡啶二羧酸配合物的合成及电化学性质的研究

Synthesis,Electrochemical Behavior of Uranium Complex with 2,5-Pyridinedicarboxylic Acid

以二氧化铀、2,5-吡啶二羧酸为原料,采用回流法合成了配合物U(C7H3NO4)3(C7H6NO4)4.3H2O,并对其进行了红外光谱、紫外光谱、元素分析及电化学性质分析等表征。循环伏安结果表明,该配合物有两对氧化还原峰,电子转移发生在电对U(Ⅵ)/U(Ⅴ)和U(Ⅴ)/U(Ⅳ)。配合物U(C7H3NO4)3(C7H6NO4)4.3H2O具有良好的氧化还原电化学性能。

Uranium-containing H2 PDA （H2 PDA = 2,5-pyridinedicarboxylic acid） complex was obtained by the reaction of UO2 and H2 PDA in the way of reflux. The complex was characterized by IR,UV,elemental anal-ysis and cyclic voltammetry（CV）. CV study revealed the complex had two redox peaks and electron transfer oc-cured between the electron doublets U（ Ⅵ ）/U（ Ⅴ ）, U（ Ⅴ ）/U（ Ⅳ ）. The complex exhibited good redox electro-chemical performance.
