Analyzer Principle and Application of Orthophosphate



The yellow phosphomolybdic heteropoly acid was produced by the reaction of orthophosphate with ammonium molybdate in acid solution, and then reduced to phosphomolybdic blue by ascorbic acid.

The main application scenarios are the monitoring of enterprise rainwater and sewage, the monitoring of total copper content in municipal pipe network, pumping station, groundwater, river water, lake water and sea water.
