以聚苯胺（ＰＡｎ）薄膜修饰铂丝电极为基体电极，将含有尼古丁－四苯硼钠的聚氯乙烯（ＰＶＣ）敏感膜涂渍于基体电极表面，制成全固态双膜尼古丁电极。在ｐＨ值为５．５～７．０范围内，对８．０×１０－６～１．０×１０－２ｍｏｌ·Ｌ－１的尼古丁水溶液有良好线性响应，斜率为５８ｍＶ·ｄｅｃ－１，检测下限为４．５×１０－６ｍｏｌ·Ｌ－１。该电极结构简单，稳定性好，可用于测定烟草和卷烟烟气粒相物中的尼古丁。
Polyaniline (PAn) thin film modified platinum wire electrode as the base electrode, the nicotine - sodium tetraphenylborate containing polyvinyl chloride (PVC) sensitive film coated on the surface of the substrate electrode, made of solid-state double membrane nicotine electrodes. In the pH range of 5.5-7.0, there was a good linear response to nicotine aqueous solution of 8.0 × 10-6 ~ 1.0 × 10-2mol·L-1, the slope was 58mV · dec-1, The detection limit is 4.5 × 10-6mol·L-1. The electrode has the advantages of simple structure and good stability, and can be used for measuring nicotine in tobacco and cigarette smoke particulate matter.
