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.
