Scope

This document specifies the determination method of copper, iron and zinc content in
industrial circulating cooling water and scale in boiler water system or circulating water
system - atomic absorption spectrometry.
This document is applicable to the determination of copper content of 0.1mg/L~20mg/L,
iron content of 0.1mg/L~20mg/L and zinc content of 0.1mg/L~20mg/L in industrial
circulating cooling water; the determination of copper content ≥ 0.005%, iron content
≥ 0.01%, zinc content ≥ 0.005% in scale.
This document is also applicable to the determination of copper, iron and zinc in boiler
water and the determination of copper, iron and zinc in scale in other industrial water,
raw water and water systems, as well as the determination of zinc content in
phosphorus-zinc pre-film solution for industrial circulating cooling water.
