Continuous Water Quality Monitoring Equipment for Measuring Total Phosphorus
Product Introduction
The potassium persulfate oxidation-ammonium molybdate spectrophotometry is adopted for WS1504 continuous water quality monitoring uquipment for total phosphorus content. In an acidic medium, orthophosphate reacts with ammonium molybdate to generate phosphomolybdenum heteropolyacid in the presence of antimony salt, which is immediately reduced by ascorbic acid to form a blue complex. This substance has a maximum absorption at 700nm. According to the Lambert-Beer law, the total phosphorus content in the water sample is measured through the photoelectric colorimetric method.
