那可汀在水／1，2－二氯乙烷微界面转移的机理研究及分析测定

The Study of the Mechanism on Narcotine Transfer Across the Water/1,2-Dichloroethane Interface and the Detection

本文用循环伏安法研究质子化那可汀在水／１，２－二氯乙烷微界面的转移机制，计算了与界面转移有关参数，并且研究了那可汀的界面电位响应，将那可汀液／液界面微电极用于测定人尿中那可汀含量，回收率为９２％～１０６％，检测下限为３×１０－５ｍｏｌ／Ｌ。

In this paper,on the base of the study of the mechanism on protonated narcotine transfer across the water/1,2-dichloroethane interface by cyclic voltammetry method,some parameters relating to the interface transfer have been calculated, and the interface potential response ofnarcotine has also been studied.We have succeeded in applying the narcotine liquid/liquid interfsce microelectrode to determine the narcotine in urine.The recovery is 92%-106%,the detection limit is 3×10-5mol/L.
