In the presence of sodium nitroprusside, ammonium and salicylate and hypochlorite ions react to produce blue compounds, and then by photoelectric colorimetric method to measure the content of ammonia in water samples, measured values displayed by the screen.

In acidic medium, orthophosphoric acid reacts with ammonium molybdate to form phosphomolybdic heteropoly acid in the presence of antimony salt and then is reduced by ascorbic acid immediately to form a blue complex. The water sample is then measured by photoelectric colorimetry In the total phosphorus content, measured by the display screen display.
