Description

Refill kit for nitrate visual test kits used for water analysis. Includes 30 self-filling ampoules, acidifier solution, buffer solution, and zinc.

  • Nitrate is reduced to nitrite by shaking the sample with a zinc metal catalyst and a citrate buffer.
  • The nitrite is reacted with sulfanilic acid and N-(1-naphthyl)ethylenediamine dihydrochloride (NED) in an acidic solution to produce a intense reddish-purple azo dye. Results are expressed as ppm (mg/L) nitrate-nitrogen (NO3-N). This method is applicable to industrial wastewaters, drinking, and surface waters. These Nitrate in water test kits can also be used for the analysis of seawater. To convert results from ppm NO3-N to ppm NO3, multiply by 4.43.
