Atomic emission of anhydrous hydrogen bromide: spectra from 200 to 900 nm by sealed inductively coupled plasma-atomic emission spectroscopy

摘要

Anhydrous hydrogen bromide, at concentrations of up to 25%, has been introduced into a sealed inductively coupled plasma system for spectrochernical analysis. The emission spectra of 15% anhydrous hydrogen bromide is reported over the spectral range of 200 to 900 nm from an enclosed inductively coupled plasma discharge operated at atmospheric pressure and 1.1 kW. More to 140 atomic Br I lines are identified and reported along with their relative, intensities, Where possible, molecular band assignments of Br_2 are made, Impurities identified qualitatively include Fe, Sn, C, and Ni. The presence of these impurities were verified by gas phase hydrolysis and subsequent inductively coupled plasma-mass spectrometry analysis.
