Kinetic studies provide essential information to design efficient photocatalytic devices. Nevertheless, reliable parameters are difficult to obtain in conventional reactors. Alternatively, microreactors provide an excellent platform for photocatalytic kinetic studies: laminar flow, short molecular diffusion distances, uniform irradiation, large surface to volume ratio, and accurate control of operation variables. Additionally, small amounts of catalysts and reagents are needed, and results can be obtained employing short assay times. In this study, we present a simple method for obtaining kinetic parameters of the degradation of binary mixtures of pollutants in a photocatalytic microreactor. The degradation of the synthetic hormone 17-α-ethinylestradiol (EE2) was evaluated in the presence of different amounts of phenol.
