GB/T 13689-2007 Water for industrial circulating cooling system and boiler—Determination of copper
Abstract
This standard specifies the methods for determining the copper content in natural water, industrial circulating cooling water, and boiler water. In this standard, the zinc reagent method is applicable to the determination of copper content in water samples such as boiler feedwater, condensate water, steam, water-cooled generator cooling water, and boiler water, with a range of 2.5 μg/L to 50 μg/L; the sodium diethyldithiocarbamate spectrophotometry method is applicable to the determination of copper content in industrial circulating cooling water, various industrial waters, and domestic water with a range of 0.01 mg/L to 2.00 mg/L; and the direct photometry method with sodium diethyldithiocarbamate is applicable to the determination of copper content in industrial circulating cooling water without suspended solids, with a range of 0.05 mg/L to 6.00 mg/L.
