Chemical and spectral behavior of nitric acid in aqueous sulfuric acid solutions: Absorption spectrum and molar absorption coefficient of nitronium ion.

Boris G Ershov1, Nadezhda M Panich2.   

Abstract

The chemical species formed from nitric acid in aqueous solutions of sulfuric acid (up to 18.0molL-1) were studied by optical spectroscopy method. The concentration region of nitronium ion formation was identified and NO2+ ion absorption spectrum was measured (λmax≤190nm and ε190=1040±50mol-1Lcm-1).
