摘要
研究了聚苯胺修饰微电极的制备以及对溶液 pH值的响应 .讨论了不同聚合条件下所得到的聚苯胺膜对电极响应时间 ,测量的稳定性和使用寿命的影响 .在溶液的pH =2 - 12范围内 ,该电极的电位与溶液的 pH值有很好的线性关系 .相关系数为 0 .996 ,斜率为 85mv/ pH .用于样品测定 。
This paper state the preparation of polyaniline film modified Pt microelectrode and responsence to pH of solution. The influence of polyaniline film obtained under different condition on responsence time usage lifetime of electrode was discussed. In the range of pH 2-12, the linear of E-pH was observed. R was 0.995, the slope was 85mv/pH. The results of sample test are satisfactory.
