电分析化学在杂多酸（盐）研究中的应用──稀土钨砷、钨镓及钨钛杂多配合物氧化还原性质的研究

Application of Electroanalytical Chemistry in Heteropoly Compounds System──Studies on the Redox Properties of Bis( undecatungstometalate)Lanthanates

应用电化学方法，系统研究ｋｅｇｇｉｎ结构稀土取代衍生物Ｌｎ（ＭＷ＿（１１）＿２（Ｍ＝Ａｓ，Ｔｉ，Ｇａ，Ｌｎ＝Ｌａ，Ｃｅ，Ｐｒ，Ｎｄ，Ｓｍ，Ｅｕ，Ｇｄ，Ｄｙ）在溶液中的氧化还原性质，得其氧化顺序，提出还原机理。

The redox properties of Ln(MW_(11))_2(M=As, Ti, Ga; Ln=La,ce,pr,Nd,Sm,Eu,Gd , Dy ) are systematically studied.It has been found that the redox order is La(AsW_(11))_2>La(TiW_(11))_2>La(GaW_(11))_2.The reduction process of Ln(MW_(11))_2 anion has been discussed.
