Principle:
In the presence of potassium persulfate, the nitrogen-containing compounds in the water sample are completely converted into nitrate nitrogen after high digestion. The absorbance of the complex is measured by a spectrophotometer at a wavelength of 220nm and converted into a total nitrogen value.
