2Method basis for online automatic monitoring of total nitrogen water quality
Determination of Total Nitrogen in Water QualityAlkaline potassium persulfate high-temperature digestion, UV spectrophotometry (* * * standard HJ 636-2012)

Technical requirements for total nitrogen water quality automatic analyzerHJ/T 102-2003
Brief Introduction to the Principle of Total Nitrogen Water Quality Online Automatic Monitoring Instrument：
atAt 120-124 ℃, alkaline potassium persulfate solution converts nitrogen containing compounds in the sample into nitrate. UV spectrophotometry is used to measure the absorbance A220 and A275 at wavelengths of 220nm and 275nm, respectively. The corrected absorbance A and total nitrogen (calculated as N) are calculated according to formula (1), and the content is proportional to the corrected absorbance A.

A=A220-2A275
