GB/T 14637-2021 《Determination of copper,iron and zinc in industrial circulating cooling water and scale—Atomic absorption spectrometric method》 Related products

This standard specifies the method for the determination of copper, iron and zinc content in industrial circulating chilled down water and scale by atomic absorption spectroscopy (AAS). It is applicable to the analysis of scale in circulating chilled down water, boiler water and its systems. The determination range includes copper, iron and zinc content in water, and copper, iron and zinc content in scale. This standard is also applicable to the detection of Miscellaneous industrial water, providing technical support for water quality monitoring to ensure the normal operation of equipment and systems.
