摘　　要：本文运用简易示波伏安法成功地进行了药物滴定分析,测定了两种新药胃复康及氢溴酸苯甲托品,获得了满意的结果。这种方法克服双池伏安法仪器复杂等缺点,使用一个电解池和一个很简单的线路也可获得示波伏安图。它能部分地扣除充电电流,终点时峰形变化敏锐。Two new drugs called benactyzini hydrochloridum and benzatropini hydrobromidum were determined by a simple oscillographic voltammetry with satisfactory results. The new method overcomes some faults in oscillographic voltammetry of using two electrolytic cells. The if-E curve can be obtained by using an electrolytic cell and a simple circuit. It can compensate some of charging current of the electrical double layer. At end-point, the change of peak is sharp, so it can be widely applied to the titrimetric analysis of Pharmaceuticals.
