摘　　要：建立了盐酸普罗帕酮（Propafenone Hydrochloride，心律平，简称PPF）的单扫描极谱分析方法，在0．12mol．L^-1NH3·H2O-NH4Cl（pH=9．25）溶液中，盐酸普罗帕酮得到一良好的二阶导数还原峰，Ep（vs．SCE）=-1.424V。峰电流与浓度在4．0×10^-7-8．0×10^-6mol／L范围内呈良好线性关系（r=0．9994，n=11），检出限为2．0×10^-7mol／L。并研究了该波的性质及电极反应机理。用该方法测定盐酸普罗帕酮，结果令人满意。PPF showed a second - order derivative reduction wave at potential of - 1. 424V （ vs, SCE） in the 0. 12 mol · L^-1NH3 ~ H2O- NH4Cl （pH = 9.25 ） base solution by single- sweep oscilloploargraphy. The peak hight of PPF was proportional to its concentration in the ranges of 4 × 10^-7 0. 9994, n = 11 ）. The detection limit was 2. 0 ×10^-7 mol/L. mol/L to 8.0 ×10^-6mol/L for PPF was achieved, with（r = And several electrochemical methods were used to study the Fonnononetin with satisfactory results.
