TEM Online Total Nitrogen Analyzer
In the potassium persulfate digestion UV spectrophotometric method, nitrogen compounds are oxidized to nitrate ions through high-temperature digestion using persulfate. Under acidic conditions, the resulting change is measured by UV absorbance. Turbidity effects are corrected during analysis, and the total nitrogen content is calculated based on the measured absorbance.
Product Application
● Monitoring at the inlet and outlet of wastewater treatment plants
● Effluent discharge points of industrial facilities and other pollution sources
