This standard specifies the determination method of chloride ion content in industrial circulating cooling water and boiler water. The molar method and potentiometric titration method in this standard are applicable to the determination of chloride ion content in natural water, circulating cooling water, demineralized water, and boiler water. When the concentration is high, the sampling volume can be appropriately reduced and measured after dilution; the determination range of potentiometric titration is 5 mg/L~1 000 mg/L; coprecipitation enrichment spectrophotometry is suitable for the determination of chloride ion content in desalted water and boiler feed water. The measuring range is 10 μg/L~100 μg/L.
