Metal Ion Reactions with Ozone and Atomic Oxygen.
Abstract
An experiment attempting to measure the thermal and near-thermal rate coefficients for reactions of metal ions with O and O3 is summarized. The method involves a new type of drift tube made of a fully oxidized leaky dielectric material (Cerramag C-11) which permits placing of the drift field without metallic electrodes which could degrade O and O3 into O2 in surface reactions. In the experiments Al(+) from an external surface ionization source was used, the drift gas was argon to which the reactant gas was added, and ions emerging from the drift tube were mass spectrometically detected. It was found by modulated beam mass spectrometry that ozone was not degraded in the drift tube; the atom content in partially dissociated oxygen admitted to the tube was too low to get unequivocal data on the integrity of O in the tube.
