Nitrate as NO3 Test Kit

OverviewSpecificationsResources
Procedure: Small amount of sample is collected in a test tube and the corresponding reagent is added to the sample. Color of the sample changes and the same is compared with the respective color chart. The reading of the matched color on the color chart is the concentration of the respective parameter in the water.

Cadmium metal reduces nitrates in the sample to Nitrite. The Nitrite ion reacts in an acidic medium with sulfanilamide to form an intermediate diazonium salt. The salt couples with NEDA to form a mezanta colored product, which is proportional to Nitrate concentration.
