Abstract
Absorption spectrum and the yield of e aq − determined in quaternary benzene/water and dodecane/water microemulsions were found to be identical with those in pure water. This indicates that the excess electrons produced in the oil droplets cross the oil/water interface and appear in the aqueous phase as hydrated electrons. On the contrary, it was found that the OH radical yield measured by converting into (SCN) 2 .− was directly proportional to the water content and there was no contribution from the oil phase. The e aq − decay in aerated microemulsion showed that the [O 2] in the aqueous phase was decreasing with continuous pulse irradiation and the estimated G(–O 2) in the oil was higher than in water. However, peroxides were predominantly formed in the aqueous phase and almost not in the oil. Rate constants for the addition of e aq − and OH to benzene in the benzene/water microemulsion and the following bimolecular decay of cyclohexadienyl and hydroxycyclohexadienyl radicals agree well with those reported in aqueous solutions.
