The orthophosphate level in mg/L (or ppm) is determined by a colorimetric method. Ammonium molybdate and potassium antimonyl tartrate react in acid medium with orthophosphate to form a phosphomolybdate complex that is reduced to intensely coloured molybdenum blue by ascorbic acid. The colour intensity of the solution determines the phosphate concentration. Phosphates can be classified as ortho, condensed or organically bound. As with existing test kits on the market, the HANNA Phosphate Test Kit will only determine ortho phosphate levels. The test kit is supplied with the following; 20 ml plastic beaker, colour comparison cube and 50 packets phosphate reagent.
