The application of the UV process alone showed low efficiency, which was attributed to the presence of UV-absorbing material. In addition, the photolysis of fluorene compared with the two other PAHs was significantly retarded when the fluorene was present in surface waters however, the oxidation rates of the three PAHs were essentially independent of the water type. It was concluded that the elimination of PAHs is mainly due to HO generated from hydrogen peroxide photolysis. In order to simplify the kinetic treatment, the pseudo first-order kinetics is used to determine the... [Pg.260]

The numerator of Equation (7.64) represents the production rate of hydroxyl radicals by hydrogen peroxide photolysis. When several UV absorbers are present, the fraction of radiation absorbed by peroxide to produce the hydroxyl radicals will be smaller. The denominator of Equation (7.64) represents the consumption rate of hydroxyl radicals by key scavengers. The value of /M and fPER denotes the relative importance of the destruction... [Pg.284]

In addition to the photolytic ozonation experiments described above, hydrogen peroxide photolysis experiments were performed in the presence and absence of hydroxyl radical scavengers. These experiments were run using distilled water (a) as it came from the lab reservoir, (b) after oxygenation, and (c) after sparging with nitrogen to remove oxygen. The results are shown in Table I, in the form of the observed rate constants. [Pg.79]
