Scope

This standard specifies the determination method of copper content in natural water, industrial circulating cooling water and boiler water. The zinc reagent method in this standard is applicable to the determination of the copper content of 2.5 μg/L to 50 μg/L in water samples such as boiler feed water, condensed water, steam, water internal cooling generator cooling water and boiler water; diethyldithioamino Sodium formate spectrophotometry is suitable for the determination of copper content of 0.01 mg/L to 2.00 mg/L in industrial circulating cooling water, various industrial water and domestic water; direct photometry of sodium diethyldithiocarbamate is suitable for the determination of copper content without suspended solids Determination of copper content 0.05 mg/L to 6.00 mg/L in industrial circulating cooling water.
