A new conductive polymer H ~ + ion sensor with hydrogen function was obtained by electrochemical treatment of the polypyrrole film electrode prepared by electrochemical method. The electrochemical properties of the membrane electrode, the hydrogen ion response mechanism, the polymerization conditions and the different treatment Effect of the method on the electrode potential response. The membrane electrode exhibits a Nernst response to pH within the range of pH 3 to pH 12 with an electrode coefficient of 57 mV / pH and high anti-interference to Li ~ +, Na ~ + and K ~ + ions. The electrode has a small internal resistance, response block, preparation is simple, wide response range and so on.
