WDet-5000 Total Nitrogen Water Quality Online Automatic Analyzer

Product Description
 
Under more than 60℃ in aqueous solution, potassium persulfate can be completely decomposed into potassium bisulfate and atomic oxygen, and at 120℃~ 124℃ conditions, the atomic oxygen can make the nitrogen of nitrogen compound in water samples element oxidize to nitrate, andorganic matter are also oxidized and decomposed simultaneously. The absorbance of water samples is measured by UV spectrophotometry at the wavelength of 220nm and 275nm. Total nitrogen content is calculated according to this absorbance.
