应用十六烷基三甲基溴化铵对蒙脱石进行改性,成功地制备稳定性良好的异咯嗪蒙脱石修饰电极.用循环伏安法对此修饰电极的电化学行为进行了研究,测定了异咯嗪在蒙脱石膜内的化学扩散系数,对异咯嗪在改性蒙脱石中电极反应机制进行了探讨
A cyclic voltametric investigation of stability and redox properties of isoalloxazne on cetytrimethyammonium bromide(CTAB) modified montomorillonite clay platinium electrode in aqueous solution has been performed. pH dependent film concentrations and apparent diffusion coefficents were measured. The mechanism of the charge transport process with in the clay film were discussed.
