- Abstract
- Several fuel-rich laminar, H2/O2/N2 flames seeded with potassium salts are employed in an investigation of the thermodynamics and kinetics of electron attachment phenomena produced by molydbenum, chromium, vanadium and boron additives. Mass spectrometry, electrostatic probes, microwave resonant cavity techniques, and optical spectroscopy are used to determine negative and positive ion identies, positive ion concentrations, electron concentrations and neutral species concentrations, respectively. It is shown that addition of molybdenum-containing compounds to flames seeded with potassium causes large reductions in concentrations of potassium atoms and extensive electron attachment.
