WS1509 Orthophosphate Water Quality Online Automatic Monitor

Product overview

Orthophosphate in the sample to be tested reacts with ammonium molybdate in an acidic medium, in the presence of antimony salts, to produce Molybdophosphate heteropoly acid which are immediately reduced by ascorbic acid to produce a blue color complex. The complex has maximum absorption at a specific wavelength, and the content of orthophosphate in the sample to be tested is calculated by photoelectric colorimetry.
