Nitrite in Water

Description

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).

Usage

Nitrite (Conc_std_sol, E1, E1_s, E0, EB1)

Arguments

Conc_std_sol	Concentration of standard solution
E1	Absorbance of standard with reagent
E1_s	Absorbance of sample with reagent
E0	Absorbance of sample without NEED reagent
EB1	Absorbance of distilled water and reagent

Value

Nitrite (micro gm/L)
