摘要：

In this paper, the electrochemical behaviour of molibdosilicic heteropoly complex with dysprosium K10H3[Dy(SiMo11O39)(2)]. xH(2)O [denoted as Dy(SiMo11)(2)] was studied. Voltammetric behavior of this complex was greatly influenced by pH of solutions. The polypyrrole (PPy) film doped with this complex was prepared by electropolymerization of pyrrole in the presence of Dy(SiMo11)(2) under potential cycling conditions. The microenvironment within the PPy film has an effect on the electrochemical behavior of Dy(SiMo11)(2) entrapped in the film. The film electrode can catalyze the reduction of ClO3- and BrO3-.
