- Modelling and designing of photoreactor for phenol degradation in wastewater using MATLAB

I researched the solar collectors implemented in practice for water detoxification and I found out that the preferred design is the Compound Parabolic Concentrator. Knowing that I have no information regarding radiation beyond what's taught generally in heat transfer courses in chemical engineering to understand the models that describe the possible attenuation from absorption of photons by reacting molecules. I decided to use the simplest model of all, Lambert-Beer model, which consider that light passes through a fully homogenous media, and that no scattering takes place. But since I am not experimentally investigating phenol degradation I don't know whether the media partially absorbs light or is non-absorbing. Also, I decided to apply the catalyst as a thin fixed-film instead of a suspended form.

I also haven't decided on the geometry of the reactor I will work with, flat or tube. However, I found out that the tube is a natural choice for design because it is able to withstand the operating pressures anticipated for fluid circulation but one of the main limits of tubular configuration is the uneven or partial photocatalyst's irradiation. Moreover, the uneven flow distribution also limits the amount of water in contact with the photocatalyst, negatively influencing the overall photoreactor performances.

where can I find the reaction scheme for the photocatalytic oxidation of phenol to derive the kinetic model?
