《GB/T 13689-1992工业循环冷却水中铜的测定二乙基二硫代氨基甲酸钠分光光度法》由TC63（全国化学标准化技术委员会）归口，主管部门为中国石油和化学工业联合会。
本标准规定了工业循环冷却水中铜的测定方法。本标准适用于工业循环冷却水中铜含量0.02~2.00mg／L的测定，也适用于各种工业用水及生活用水中铜的测定。

Scope

This standard specifies the determination method of copper in industrial circulating cooling water. This standard applies to the determination of copper content of 0.02-2.00mg/L in industrial circulating cooling water, and also applies to the determination of copper in various industrial and domestic water. Iron, manganese, nickel and cobalt also form colored complexes with sodium diethyldithiocarbamate, which interferes with the determination of copper. This method uses ethylenediaminetetraacetic acid disodium salt and ammonium citrate to mask and eliminate.
