Intrinsic kinetic parameters useful for the design, optimization and comparison of photocatalytic devices, are difficult to obtain in conventional reactors. Carefully planned experiments must be carried out, along with complex models, to take into account the influence of radiation, mass transfer and fluid dynamics on the reaction rate. In turn, microreactors provide an excellent platform for photocatalytic kinetic studies because of the advantages of the microscale: laminar flow, short molecular diffusion distances, uniform irradiation, large surface to volume ratio, and accurate control of operation variables [1,2]. In this work, a simple method for obtaining kinetic parameters for first order reactions is developed. The degradation of the pollutant 4-chlorophenol (4-CP) is evaluated in a photocatalytic microreactor under different flow rates and constant UV illumination.
