摘要：

The relative importance of free radical and direct ozonation/photolysis oxidation of micropollutants in water can be estimated from simple kinetics of aqueous ozonation reactions provided these reactions develop in the slow kinetic regime of absorption. Knowledge of kinetic expressions of free radical initiation reactions and direct ozone-micropollutant or UV radiation-micropollutant reactions (and corresponding parameters: reaction rate constants, quantum yields, etc.) allows an estimation of the reaction rate ratios for any micropollutant in the ozone alone and combined with hydrogen peroxide and/or UV radiation oxidation systems.
