| Abstract: | 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. |
