TTP-1HK expandable intelligent total phosphorus analyzer

The TTP-1HK scalable smart total phosphorus analyzer is designed to be simple, reliable, consistent, and provide accurate readings. With an uninterrupted spectrum in the 320-1100nm wavelength range, the total phosphorus tester can conduct qualitative and quantitative analysis of sample substances in the visible and near-infrared spectral regions; the instrument can be expanded to more than 60 measurement programs, including CODcr, ammonia nitrogen, total phosphorus, total phosphorus, and total phosphorus. Nitrogen, residual chlorine, heavy metals and many other testing items.

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.
