Hinweis zur Analyse

Anwendungstechnischer Testentspricht

This MQuant^® Nitrite test (formally MColortest^®) is suitable for the colorimetric determination using the easy to use color card. The evaluation considers the untreated sample so even turbid and colored water samples can be analyzed without further preparation. Nitrite is naturally present in soil, water and food and must be closely monitored in drinking and ground water as well as in process, waste, or aquarium water.
The test can be used in:

• Groundwater and surface water, seawater
• Drinking water and mineral water
• Aquarium water (freshwater and seawater), waters from aquaculture
• Food after appropriate sample pretreatment
• Soils and fertilizers after appropriate sample pretreatment
• Boiler and boiler feed water, cooling water
• Wastewater
• Electroplating wastewater

Method
In acidic solution nitrite ions react with sulfanilic acid to form a diazonium salt, which in turn reacts with N-(1-naphthyl)ethylenediamine dihydrochloride to form a red-violet azo dye. The nitrite concentration is measured semiquantitatively by allocating the color to a value on a reference scale.
