The Photometer 7500 utilises the globally recognised DPD method, making testing quick and easy. In test kits employing the vanadomolybdophosphoric acid method, phosphate reacts with ammonium molybdate under acid… Phosphates that respond to colorimetric tests without preliminary hydrolysis or oxidative digestion of the sample are termed “reactive phosphorus.” While reactive phosphorus is largely a measure of orthophosphate, a small fraction of any condensed phosphate present usually is hydrolyzed unavoidably in the procedure. Then the orthophosphate is measured by the ascorbic acid method. Monitoring of phosphates is therefore critical, with sufficient quantities required for coating the pipes and ensuring that no lead leaches into the water. Phosphates are widely used in fertilizers to increase crop yield and health, which contributes to phosphate in the environment. Other key tests for pool and spa include pH, chlorine and turbidity.
