Scope

This Standard specifies the method to determine chloride content in water for industrial
circulating cooling system and boiler.
The molar method and potentiometric titration method in this Standard are applicable
to the determination of chloride content in natural water, circulating cooling water,
softened water and boiler water. The determination range of molar method is
3mg/L~150mg/L. When it exceeds 150mg/L, the sampling volume can be appropriately
reduced. Determine after dilution. The determination range of potentiometric titration
method is 5mg/L~1000mg/L. Coprecipitation and enrichment spectrophotometry
method is suitable for the determination of chloride in demineralized water and boiler
feed water. The determination range is 10μg/L~100μg/L.
