中文摘要：

在含有邻苯二胺和三乙醇胺（TEA）的酸性溶液中,用循环伏安法（CV）在铂电极上制备聚邻苯二胺（PoPD）薄膜。通过对该薄膜进行深入的电化学分析,并将结果与无三乙醇胺参与的聚邻苯二胺的性能进行比较,发现在三乙醇胺参与下得到的聚邻苯二胺薄膜在铂电极表现出更好的粘附性,同时在氢离子选择性电极方面表现出优良的性能。在pH 2-13范围内具有良好的Nernst响应,直线斜率为59.62 mV/pH,相关系数达0.99以上,碱性条件下响应时间可缩短至30 s左右。该电极对大多数普通干扰物具有较好的选择性,可用于实际样品的测试。

英文摘要：

At room temperature, the poly-o-phenylenediamine （PoPD） thin films were modified on the surface of platinum electrode in acid media in the presence of triethanolamine （TEA） using an electrochemical method. The polymer films were further characterized by electrochemical analysis and the results were compared with those obtained in the absence of TEA. The presence of TEA showed improvement in adherence, reproducibility and stability of the films. The potential equilibrium response time was faster. In the alkali condition, the response time was approximately 30 s. The potentiometric responses appeared reversible and linear to pH changes in the range from pH 2 to 13 with a slope of 59.62 mV/pH and a correlation coefficient of R = 0.999. This modified electrode could efficiently prevent the interference of general ions and could be used for the sample test.
