Název v původním jazyce

A SIFT Study of the Reactions of H3O+, NO+ and O2+ with Hydrogen Peroxide and Peroxyacetic Acid.

Popis výsledku v původním jazyce

We have carried out a selected ion flow tube, SIFT, study of the reactions of H3O+, NO+ and O2+ ions with hydrogen peroxide, H2O2, in the presence of excess water vapour and peroxyacetic acid, CH3C(O)OOH, in the presence of comparable concentrations of acetic acid, CH3COOH. This study was initiated to investigate if these peroxides could be analysed in humid air using selected ion flow tube mass spectrometry, SIFT-MS, using the above precursor ions. Rate coefficients and product ions have been determined for the NO+ and O2+ reactions with H2O2 molecules (H3O+ ions do not react at a measurable rate with H2O2 molecules) and for the rapid reactions of H3O+, NO+ and O2+ with CH3C(O)OOH molecules. It turns out that both H3O+ and O2+ ions are unsuitable forSIFT-MS analyses of these peroxides, either because of low reactivity and/or the production of common product ions for their reactions with H2O and CH3COOH molecules.
