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
