三乙酰丙酮镧(镨)的合成及电化学性质

Synthesis and Electrochemical Properties of Lanthanum and Praseodymium Triacetylacetonate

合成了三乙酰丙酮镧镨 (L a,Pr)配合物 ,利用循环伏安法研究了配合物的电化学性质 ,结果显示 :在3m mol L a(acac) 3 或 Pr(acac) 3 的乙腈溶液中 ,产生三个氧化峰和三个还原峰 ,根据循环伏安图 ,推出氧化 -还原反应机理 ,同时对影响循环伏安图的因素进行了研究。

La(acac) 3 and Pr(acac) 3 were prepared in this paper.The electrochemical behaviors of them on glass-carban electrode were investigated.In 3mmol·L -1La(acac) 3 or Pr(acac) 3 acetonitrile solution,three oxidation peaks and three reduction peaks were found.The mechanism of redox was put forward,and factors of influence on electrochemical properties were discussed.
