Title

Spectrophotometric Method for Nitroglycerine Analysis in Air

Abstract

A method for the spectrophotometric analysis of nitroglycerine (NG) in gaseous effluents is developed. The procedure is based on the conversion of NG to nitrite ions by dissolving NG in an absorbing alkaline solution. Nitrite ions were analyzed spectrophotometrically by reacting the sample with hydrogen peroxide, a mixture of sulfanilamide and phosphoric acid, and N-(1-naphthyl)ethylenediamine dihydrochloride, successively. NG concentrations were determined from absorbances at 540 nm via specially developed calibration graph. The detection limit is about 0.1 ppmv of NG in air. The selectivity of the method and the effect of NO2 presence in the sample are discussed. Estimates of NG concentrations correlate well with those obtained by chromatographic method. © 1994, American Chemical Society. All rights reserved.
