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...

Nitrite/nitrate speciation through arsenomolybdenum blue complex at trace level: Application to Biological and Environmentalsamples,AnalyticalMethods,3,1838-1844(2011). (публикация автора на scipeople)   

Y.Venkataramanappa and M.Pandurangappa - Analytical Methods , 2011
A novel and simple method has been proposed for the estimation of nitrite/nitrate based on the reduction of arsenomolybdic acid to arsenomolybdenum blue using ascorbic acid. The obtained arsenomolybdenum blue complex has been oxidized by the addition of nitrite and the decrease in the absorbance of ...

Flow injection analysis of ambient nitrogen oxides using Rhodamine B hydrazide as a chemosensor (публикация автора на scipeople)   

Y.Venkataramanappa and M.Pandurangappa , 2012
A new chemosensor has been used to monitor atmospheric nitrogen oxides [NO + NO2] at ppb level. It is based on the catalytic reaction of nitrogen oxides with rhodamine B hydrazide to produce a colored compound through the hydrolysis of the amide bond of rhodamine B hydrazide. A simple spectrophotome...
