研究了碳纤维（CF）上掺杂氯离子的聚吡咯（PPY）膜微盘电极的电位响应。讨论了聚合条件对响应特性的影响。电极的最佳制备条件为：在0.1- 0.2M吡咯（Py）中，含0.1MLiCl，循环电位为+0.8 ~+1.0V，电聚合时间为15-20 min，电极的能斯特响应为56-58 mV/pCl，检出限为3.6 × 10 - 5 MCl。它具有电阻低、调理时间短、响应速度快等优点。用于血清中氯化物的测定，结果满意。
The potential-response of a microdisk electrode made with a chloride-doped polypyrrole (PPY) film on a carbon fibre (CF) has been examined. The effect of the polymerization conditions on the response characteristics is discussed. The optimum conditions for preparing the electrode are: cycling potential from +0.8 to +1.0 V in 0.1–0.2Mpyrrole (Py) containing 0.1MLiCl, electropolymerization time 15–20 min. The electrode gives a Nernstian response of 56–58 mV/pCl and a detection limit of 3.6 × 10−5Mchloride. It has the advantages of low resistance, short conditioning time and fast response. It has been used satisfactorily for detection of chloride in serum.
