Abstract

A Molecular rotational resonance (MRR) spectrometer, which operates in the 18-26GHz, has been evaluated for monitoring the oxidation process of SO₂ and O₂ in the presence of NH₄VO₃. This work is performed as a part of effort to determine the utility of rotational spectroscopy as a tool for monitoring the conversion of SO₂ to H₂SO₄. The initial MRR measurements revealed the reduction of SO₂and the presence of small polar impurities (i.e., water vapor and ammonia). The current data have been further employed to validate K-Band MRR for SO₂ removal. The MRR maintains its linearity confirming its strength to monitor the removal of SO₂ in presence of other polar impurities. Work to improve this analytical procedure is underway and will be reported in this talk.
