    Abstract The electrochemical polymerization of azure at glassy carbon electrode in phosphate buffer solution and

    the properties of the polymerization films have been studied. The poly(azure Ⅰ) modified electrode exhibits three

    peaks over the potential range of + 0. 8～ - 0. 8 V ( vs .AgP AgCl) . The peak potentials are Ep

    1

    = + 0. 123 V , Ep

    2

    = - 0. 432 V and Ep

    3

    = - 0. 125 V ( vs . AgP AgCl) respectively. The poly(azure Ⅰ) modified electrode shows a ......
