通过研制双膜流通式烟碱电极，建立了流动注射电位法测定烟碱的新方法。用磷酸二氢钠－磷酸氢二钠缓冲溶液合并１．０×１０－５ｍｏｌ／Ｌ的烟碱标准溶液作载液，对１．０×１０－４～１．０×１０－１ｍｏｌ／Ｌ的烟碱溶液有良好线性响应，相关系数０．９９８５。本方法简便、选择性好，进样频率８０次／ｈ，适合大批量样品的快速测定，用于检测卷烟烟气粒相物中的烟碱，结果较满意。
A new method for the determination of nicotine by flow injection potential was established by developing a dual-membrane flow-through nicotine electrode. 1.0 × 10-5mol / L nicotine standard solution was combined with sodium dihydrogenphosphate-disodium hydrogen phosphate buffer solution to carry out the reaction of 1.0 × 10-4 ~ 1.0 × 10-1mol / L Nicotine solution has a good linear response, the correlation coefficient of 0.9985. The method is simple, selective, and the injection frequency is 80 times / h. It is suitable for the rapid determination of large quantities of samples and is used to detect the nicotine in cigarette smoke particulate matter. The results are satisfactory.
