Webdetermination of phosphorus is based on an ammonium molybdate reaction, followed by stannous chloride reduction of the complex in acidic medium, which is catalyzed by phosphate ion producing a complex known as molybdenum blue2. The method has been carried out in flow injection systems for phosphorus determination in natural waters3-6. WebA sample containing the phosphate is mixed with an acid solution of Mo VI, for example ammonium molybdate, to produce PMo 12O3− 40, which has an α- Keggin structure. This anion is then reduced by, for example, ascorbic acid or SnCl 2, to form the blue coloured β-keggin ion, PMo 12O7− 40.
