摘　　要：本文研制了基于双节式微滴管顶端的１，２－二氯乙烷／水界面的微电极，利用循环伏安法、不对称扫描循环伏安法、溶出伏安法对苏卡因的转移机制进行了详细研究，计算了有关界面转移参数，分析检测限为６．８×１０（－６）ｍｏｌ／Ｌ，平均回收率９８．７％。A dubcaine microelectrode based on a 1,2-dichloroethane/water (DCE/W) iuterface supported at the tip of a dual-section micropipette was investigsted by cyclic voltammetry, asymmetric voltammetry and stripping voltammetry. Trace dubcaine was determined down to 6. 8 × 10-6 mol/L in sample solution, and average recovery was 98. 7%. Some transfer data of dubcaine was also obtained.
