摘　　要：本文报道在[NiFe(CN)_6]^(2-/1)化学修饰膜上电化学聚合生成聚(1,2-二氨基苯)膜化学修饰电极的制备方法,实验结果表明该电极制备方法简便、性能稳定、电极电位对溶液pH值变化敏感,在pH4～10范围内电位响应与pH呈直线关系,斜率为54mV,具有作为pH传感器的前景。This paper reports the method of electrochemical polymerization to produce poly (1,2- Diaminobenzene ) film chemically modified [NiFe (CN)_6]^(2-/1-) electrode. The experimental results show that this method of preparation is simple and convenient. The electrode properties are stable and the electrode potential respones is sensitive to change of pH in solution. The pH response is nearly Nernstian with a slope of 54mV and a linear correlation coefficient of 0.992.
