TCNP-3HK Expandable Intelligent COD Ammonia Nitrogen Total Phosphorus Analyzer

TCNP-3HK Expandable Intelligent COD Ammonia Nitrogen Total Phosphorus Analyzer

Principle of COD test: rapid resolution spectrophotometry
Water sample, potassium dichromate solution, silver sulfate solution (silver sulfate as a catalyst can be added more effectively to oxidize straight chain fat
Compound) and concentrated sulfuric acid mixture heated to 165℃, dichroic acid ion oxidation of organic compounds in the solution after the color will change, in the instrument measurement range, the degree of color change and COD concentration in the sample is proportional to, therefore, by spectrophotometry measurement of the degree of color change, you can calculate the concentration of COD in the sample.

Ammonia nitrogen test principle: Nesser's reagent spectrophotometry
Ammonia nitrogen in the form of free ammonia or ammonium ion reacts with Nessler's reagent to produce a reddish brown complex. The absorbance of the complex is proportional to the content of ammonia nitrogen, and the absorbance is measured at the wavelength 420nm.

Total phosphorus test principle: ammonium molybdate spectrophotometry
The polyphosphates and other phosphorus compounds in water are hydrolyzed under high temperature and high pressure acidic conditions to form phosphate, and for other phosphorus compounds that are difficult to oxidize, they are oxidized to phosphate by strong oxidants. Phosphoric acid ions in a strong acid solution containing molybdate, generate an antimony compound, this compound is reduced to blue phosphomolybdate by reducing agents, generating blue complex, in the instrument measurement range, the degree of color change and the total phosphorus concentration in the sample is proportional to, therefore, by spectrophotometry to measure the degree of color change, you can calculate the concentration of total phosphorus in the sample.
