Nitrite

Nitrite is the key part of the nitrogen cycle in water. During denitrification, which occurs in low oxygen conditions, nitrite can build up. High levels of nitrite are harmful to fish, shrimp, and other aquatic organisms, making it important to manage for their health and well-being.Principle of analysis:Sulphanilamide is used as the amino compounds which is coupled with n-(1-napthyl)-ethylene diamine dihydrochloride. This reaction leads to the formation of azo dye formed is proportional to the initial concentration of nitrite. Absorbance is measured 543nm in spectrophotometer. APHA(2017,ISBN:9780875532875).

Nitrite in Water

A varied array of mathematical derivations from various titrimetric and colorimetric methods for analyzing water quality parameters were condensed and integrated for the better physicochemical analysis. It is indispensable for managing any aquatic ecosystem, including aquaculture facilities. By substituting titrant and spectrophotometric absorbance readings, accurate determination of the concentrations of critical parameters such as Dissolved Oxygen, Free Carbon Dioxide, Total Alkalinity, Water Hardness, Hydrogen Sulfide, Total Ammonia Nitrogen, Nitrite, Nitrate, Chlorinity, Salinity, Inorganic Phosphate, and Transparency can be facilitated APHA(2017,ISBN:9780875532875).
