Product Introduction:

Nitrogen phosphorus online reagentSuitable for online analysis of total nitrogen and total phosphorus, it can be parallel applied to common imported instruments. For example, Hash NPW-160 and Shimadzu TNP-4200. Can be applied to the petrochemical industry: monitoring the quality of circulating cooling water; Environmental protection industry: monitoring of wastewater discharge from key pollution sources; Water conservancy industry: water quality monitoring of surface water, Rivers and Lakes; Municipal industry: water quality monitoring of drinking water sources, monitoring of incoming water quality of water plants, and monitoring of incoming and outgoing water quality of sewage treatment plants; Research and education: Monitoring of organic matter load in water bodies during the development of water treatment processes or water quality research.

Total phosphorus: (in accordance with the national standard GB11893-89): Peroxysulfate is used as an oxidant, and heated and digested at 120 ℃ for 30 minutes to convert phosphides into phosphate ions. The total phosphorus content is measured by molybdenum blue spectrophotometry. (Measurement wavelength: 700 nm)

Total nitrogen: (in accordance with standard HJ636-2012): peroxydisulfate is used as an oxidant, and heated and digested at 120 ℃ for 30 minutes to convert nitrogen-containing compounds into nitrate ions. The pH of the sample solution is adjusted to 2-3; UV spectrophotometry is used to detect the absorbance of nitrate.
