摘要: 泰必利(Tiapridum, 简称 TIA)属苯酰胺类抗精神病药, 化学名称为 N -(2-二乙胺乙基)-2-甲氧基-5-甲烷磺酰基苯甲酰胺盐酸盐. 其极谱行为的研究未见报道, 本文用多种电化学手段研究了 TIA 在汞电极上的电化学行为, 对其吸附特性进行了探讨, 建立了单扫示波极谱测定法。

Abstract: In a supporting electrolyte of HAc-NaAc, a sensitive derivative reduction peak of Tiapride was found by single-sweep oscillopolarography. The peak potential is -1.56 V( vs.SCE). The relationship between the peak current and the concentration of Tiapride is linear from 6.0×10-7~9.0×10-6 mol/L. The detection limit is 5.0×10-7 mol/L. The method was applied for determination of Tiapride in tablet with satisfactory results. The electrode process, reaction mechanism and polarographic behavior have been discussed.

Key words: Tiapride, polarographic behavior, adsorption, determination
