摘要
用循环伏安法（CV）制备了聚吡咯亚硝酸根离子选择性电极。表征了电极的电化学性能。在1．0x10－1～5．0x10－5mol／L浓度范围内，电极电位与亚硝酸根离子浓度成良好的线性关系，Nernst响应科率为51mv／PNO2－。观察了NO2-在PPy膜中掺杂＝去掺杂过程，从而验证了电极响应是基于掺杂机理。
In this paper, NO2- PPy ion selective electrode is prepared by cyclic voltammograms,and the properties of this polypyrrole modified electrode are characterized. There's a good linear relationship between electrode potential and the concentration of NO2- within 10-1 mol/L and 5 x 10-5 mol/L. The mingling process of NO2 - on PPy film is observed on line, and the mingling machanism of the modified electrode studied.
