摘要: 用循环伏安法在二氯甲烷、二氯乙烷、乙腈、丙酮,苯腈、吡啶、二甲基甲酰胺、二甲基亚砜等不同溶剂中,研究了稀土穴醚配合物Eu(NO3)3(2,2)和Eu2(NO3)6(2,2,2)的电化学行为。测定了其氧化还原反应的半波电位及电子转移速度常数,讨论了E1/2、ks与溶剂及支持电解质的关系。

Abstract: Electrochemical reduction of europium cryptatcs Eu(NO3)3(2,2) and Eu2(NO3)6(2,2,2) were investigated by means of cyclic voltametry in dichloro-methane, dichloroethane, acetonitrile, acetone, benzonitrile, pyridine, dimcthyl-formamidc and dimethyl sulioxide, The halfwave potentials of redox reaction and electron-transfer rate constants were determined, and the effects of solvent and supporting electrolyte on E1/2and kswere discussed.
