Aminophenyl Benzimidazole as a New Reagent for the Estimation of NO2/Nitrite/Nitrate at Trace Level: Application to Environmental Samples (публикация автора на scipeople)   

Y.Venkataramanappa and M.Pandurangappa - Analytical Letters, 40: 2974–2991, 2007 , 2007
A simple and sensitive spectrophotometric method for the determination of nitrogen dioxide in ambient air and nitrite/nitrate in water and soil samples has been developed. Nitrogen dioxide in air has been fixed as nitrite ion using alkaline sodium arsenite as absorbing medium. The method is based on...

Diaminobenzene as a novel reagent for nitrite assay in environmental samples: An evidence for its mechanistic aspects, Analyticalletters,41,3342-3363(2008). (публикация автора на scipeople)   

Y.Venkataramanappa and M.Pandurangappa - Analytical Letters, 41: 3342–3363, 2008 , 2008
o-Phenylenediamine has been used as a reagent to quantify nitrites= nitrates in a variety of sample matrices. The method is based on the cyclization reaction between o-phenylenediamine and nitrite in acid medium. The amine undergoes diazotization with nitrite in the presence of acid to form the diaz...
