本文提出利用Cl~-离子本身在选定的极谱底液中出现切口或消失指示终点的示波极谱滴定法为氯根的测定试辟一条新路,它优越于“莫尔法”。1、它不受或少受有颜色或混浊溶液干扰,可直接测定;2、终点直观,方法简单测试范围较宽;3、经反复与莫尔法对照,在标准溶液或样品测定中莫尔法减空白值后的滴定剂用量与示波滴定法所消耗的几乎相等或相差极小,可以认定示波滴定法误差少准确度高;4、可以用Cl~-离子直接滴定Ag~+离子。
In this paper, the oscillopolarographic titration method using Cl ~ - ion itself as the end point of incision or disappearance in the selected polarographic solution is proposed as a new way for the determination of chloride. It is superior to the “Morph method”. 1, it is less or less subject to the interference of color or turbid solution, can be directly measured; 2, the end point is intuitive, the method is simple test range is wide; 3, after repeated comparison with the Morph method in the standard solution or sample determination The amount of titration reagent after the method of reducing the blank value is almost equal to or less than that consumed by the oscillometric titration, and the error of the oscillometric titration can be considered to be less accurate. 4, Cl ~ - ions can be directly titrated for Ag ~ + ions .
