用循环伏安法研究了1:12磷钼杂多阴离子(PMo12)薄膜修饰电极的制备及其电化学行为, 发现PMo12膜强烈地吸附在玻璃碳电极表面, 溶液氢离子在PMo12膜改性电极的电化学过程中起着重要的作用, 而其它阴离子不参与这一过程, 在循环伏安法扫描过程中PMo12膜改性电极的稳定性很好。

A monolayer of 1:12 phosphomolybdate (PMo12) was modified electrochem. on a glassy C electrode and its electrochem. behavior was studied by cyclic voltammetry (CV). The PMo12 film is adsorbed strongly on the surface of glassy C electrodes. H+ ions in the solution plays an important role in the electrochem. processes of PMo12 film modified electrodes, whereas other anions, such as Cl-, NO3-, SO42-, ClO4- and PO43-, etc., do not take part in the processes. The stability of PMo12 film modified electrodes during CV scanning is quite good.
