Abstract: A simple method for obtaining intrinsic kinetic parameters of photocatalytic, first-order reactions ispresented. The degradation of a water pollutant, the pharmaceutical drug clofibric acid (CA), was evaluated ina photocatalytic microreactor under different flow rates, TiO2 film thicknesses, and UV irradiation fluxes. Asimple analytical model was developed to calculate the first-order kinetic constant from experimental data,under conditions of negligible mass transfer limitations. The predictions of the model, as well as its range ofvalidity, were further verified against rigorous numerical calculations of the full problem (advection, diffusionand reaction).
