- Scope
- This document specifies the copper, iron and zinc content in industrial circulating cooling water and the determination method of copper, iron and zinc content in boiler water system or circulating water system water removal - atomic absorption spectrometry. This document is applicable to the determination of copper content of 0.1 mg/L to 20 mg/L, iron content of 0.1 mg/L to 20 mg/work, and amount of 0.1 mg/L to 20 mg/L in industrial circulating cooling water. This document with a copper content of 0.005%%, an iron content of more than 0.01%%, and a zinc content of more than 0.005% is also applicable to the determination of copper, iron, and zinc in boiler water and other industrial water, copper, iron, and iron in scale in raw water and water systems. Determination of zinc content, and determination of neutralization pound content in phosphorus-zinc pre-film solution for industrial circulating cooling water. Determination of zinc content in the area
