摘要
自从化学修饰电极问世以来,在电极反应过程、电极效应以及护展修饰膜类型方面进展较快。目前研究较多的是聚合物薄膜修饰电极,由于结构和化学性能的特点,对无机物修饰电极的研究也已引起重视。
A monolayer of 1:12 phosphomolybdic anion (PMo_(12)) was modified electrochemically
on a glassy carbon electrode and its electrochemical behavior was studied with cyclic
voltammetry (CV). It is shown that PMo_(12) film is adsoibed strongly on the surface of
glassy carbon electrodes, H^+ ions in the solution plays an important role in the
electrochemical processes of PMo_(12) film modified electrodes, whereas other anions, such as
Cl^-, NO_3^-, SO_4^(2-), ClO_4^- and PO_4^(3-) etc., do not take part in the processes. The following
electrochemical reactions of PMo_(12) film modified electrodes if suggested:
PMo_(12)O_(40)^(3-)+2nH^+2ne?[H_(2n)PMO_(12)O_(40)]^(3-), n=1, 2, 3, 4
The stability of PMo_(12) film modified electrodes during CV scanning is quite good.
