Phosphate molybdate complex
WebThe orthophosphate ion reacts with ammonium molybdate and antimony potassium tartrate (catalyst) under acidic conditions to form a 12-molybdophosphoric acid complex. The complex is then reduced with ascorbic acid to form a blue heteropoly compound. The absorbance of this compound is measured spectrophotometrically at wavelength 880 WebOrthophosphate reacts with molybdate in an acid medium to produce a mixed phosphate/molybdate complex. Ascorbic acid then reduces the complex, giving an intense molybdenum blue color. The measurement wavelength is 880 nm (DR 1900: 710 nm) for spectrophotometers or 610 nm for colorimeters.
