摘要
在氯化铵-氨水(pH=11)支持电解质中用微银汞膜电极进行试验,锰、铁不干扰测定,用EDTA滴定氯化钙获得令人满意的结果。对三种样品进行分析,变异系数为0.08％—0.11％。该法快速准确,适用于氯化钙主要成份的测定。
In this paper a method is described for the determination of main component in industrial calaium chloride with mercury film micro - siver electrode testing in supporting electrolyte of NH4cl - NH3. H2O （PH = 11）, Iron and manganese dont interfer the determination. This method has been successfully applied to determinate of Calcium chloride with EDTA. Three samples has been determinined and standard deviation of determination is 0.03% - 0.06%. This method is accurate, rapid and can be applied to the determination of main component in industrial calcium chloride.
