Pt. Buckley et Jw. Birks, EVALUATION OF VISIBLE-LIGHT PHOTOLYSIS OF OZONE-WATER CLUSTER MOLECULES AS A SOURCE OF ATMOSPHERIC HYDROXYL RADICAL AND HYDROGEN-PEROXIDE, Atmospheric environment, 29(18), 1995, pp. 2409-2415
The visible-light photolysis of ozone-water van der Waals complexes wa
s evaluated as a potential source of atmospheric hydroxyl radical and/
or hydrogen peroxide. These reactions were shown to account for no mor
e than 1.3% of the atmospheric burden of OH and no more than 7% of atm
ospheric H2O2. Upper limits to the production of OH and H2O2 were eval
uated in static, gas-phase ozone/water mixtures irradiated with natura
l sunlight. Upper limits to hydroxyl radical concentrations were infer
red from the catalytic destruction of ozone. Hydrogen peroxide was det
ermined by purging the bulb contents into a receiving solvent, which w
as analyzed for H2O2 by the peroxyoxalate chemiluminescence technique.
