Concentrations of ammonia in rivers and drinking water reservoirs indicate the presence of agriculture or urban pollution. When the concentration of ammonia is high, it can alter the smell and taste of water. In industrial applications, high concentrations of ammonia can cause corrosion in pipes. Ammonia is also monitored in aquariums and fish farming applications because of its toxicity to fish.
The HI 38049 test kit measures ammonia nitrogen concentration up to 3 ppm in fresh waters, employing the Nessler colorimetric method. Ammonia reacts with the reagent in basic solution to form a yellow compound. The absorbance of this colored product is proportional to the concentration of ammonia-nitrogen present in the aqueous sample.
HI 38049 test kit comes with 20 mL ammonia reagent (for fresh water), 20 mL Nessler reagent, checker disc, glass vials with caps (2) and 3 mL plastic pipette.
