GB/T 14636-2007 requires atomic absorption spectroscopy (AAS) to measure the content of calcium and mg in industrial circulating chilled down water. First pretreat the water sample to remove interfering substances. Use Atomizer to atomize calcium and mg, Light spectrum instrument to measure their absorption of specific wavelengths of light, that is, Absorbance. Linear dispersion according to the respective standards of calcium and mg, and the content is calculated by Absorbance. The standard specifies sample collection, instrument operation, measurement process and data processing methods to ensure accurate results. This standard provides a key means for monitoring the quality of industrial circulating chilled down water, helps to understand the risk of fouling, and ensures the efficient operation of chilled down systems. It is widely used in industrial production, water treatment and other fields.
