Principle

Ammonium molybdate spectrophotometric method，the principle is :Using Potassium persulfate to digest the sample and  convert all the contented phosphorus into orthophosphate. In the acid medium,with the existence of antimony salt, orthophosphate will react with ammonium molybdate and generate phospho molybdenum heteropoly aci which will be reduced by ascorbic acid immediately. The result of the reduction is the blue complex whose absorbance is in proportion to the concentration of total phosphorus.
