This standard specifies the Spectrophotometric method, spectrophotometry, for the determination of the content of melamine in water quality, which is suitable for the detection of industrial wastewater from ammunition charging. The measurement range is 0.1~ 10.0 mg/L, and the minimum detection concentration is 0.05 mg/L. The principle of the method is that melamine is heated analysis in sulfuric acid solution to generate formaldehyde, and then reacts with acetylacetone and ammonia to produce yellow dyestuff, and is measured at a wavelength of 412 nm. This method has high detection sensitivity and is suitable for environmental monitoring and quality control of industrial wastewater.
