Nitrogen phosphorus online reagent

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.
