摘　　要：本文运用示波滴定法定于水中对溶解氧、Ca^(2+)、Mg^(2+)及Cl^-离子进行测定。利用示波器观察荧光点的移动或示波极谱图切口的产生指示滴定终点。方法简便、灵敏、符合定量分析要求。可用于环境监测之中。This paper reports that oscillo-titration method may be used for the determination of soluble oxygen, Cl^-, Ca^(2+) and Mg^(2+) in the water. The end point of titration is indicated by the change of the light(for soluble oxygen and Cl^-)and the incision of the dE/dt-E curves (for Ca^(2+) and Mg^(2+)) on the screen of oscillograph.This method is available for the environmental monitoring.
