Scope

This standard specifies the determination method of copper and zinc content in industrial circulating cooling water and scale - atomic absorption spectrometry. This standard applies to industrial circulating cooling water with a copper content of 0.5 mg/L to 50 mg/L, a zinc content of 0.1 mg/L to 20 mg/L, and a scale with a copper content of 0.5 mg/g to 10 mg/g, zinc Determination of the content of 0.1 mg/g ~ 10 mg/g. This standard is also applicable to the determination of copper and zinc content in various industrial water, raw water, domestic water and boiler water scale. This standard is also applicable to the determination of zinc content in phosphorus-zinc pre-coating solution for industrial circulating cooling water.
