| Abstract: | 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. |
