Principle:
The mixture of water sample, catalyst solution and strong oxidant digestion solution is heated to 120°C. Polyphosphate and other phosphorus-containing compounds in the water sample are digested and oxidized by strong oxidants under acidic conditions of high temperature and pressure to generate phosphate. In the presence of a catalyst, the phosphate ions generate a colored complex in a strong acid solution containing molybdate. The absorbance of the complex is measured by a spectrophotometer to calculate the concentration of total phosphorus.
