| Abstract: | A new method for determination of nitrite is presented in this paper as a result of the experiment of diazo coupling reaction of sulphanilamide nitrite with 8 hydroxyquinoline. It has been showed that azo, the product of the reaction has a maximum absorbance at 502nm. The respective detection limit for NO 2, apparent molar absorptivity and others are presented as well. |
