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。
In this paper, the determination of dissolved oxygen, Ca ~ (2 +), Mg ~ (2+) and Cl ~ - ions in water by oscillometric titration method. The oscilloscope is used to observe the movement of the phosphor spot or the generation of a oscillographic polarogram incision to indicate the end point of the titration. Method is simple, sensitive, in line with quantitative analysis requirements. Can be used for environmental monitoring.
