About this item
Nitrate is reduced to nitrite using cadmium as the reducing agent. The resulting nitrite concentration is then determined colorimetrically. This method is applicable to drinking and surface waters, as well as domestic and industrial wastes.
- Ideal for low- to medium-range colorimetric analysis of water quality
Nitrate is the most completely oxidized form of nitrogen. It is formed during the final stages of biological decomposition, either in wastewater treatment facilities or in natural water supplies. Low-level nitrate concentrations may be present in natural waters. However, a Maximum Contaminant Level of 10 ppm nitrate-nitrogen has been established for drinking water by the USEPA.
Applications: Industrial wastewater influent and effluent, industrial process waters, boiler water, cooling water, surface and ground water, potable water. Not applicable for seawater.
