Abstract

The conditions of the oxidation of various scavengers in aqueous solution by atomic hydrogen introduced from the gas phase were investigated experimentally and theoretically. Approximate equations are derived for the kinetics in the case of purely diffusion controlled mass transfer of H atoms and for the case of forced convection. First-order reaction with the scavenger in competition with second-order recombination, as well as consecutive scavenging mechanisms are considered. The results are compared with the treatment based on homogeneous kinetics.
