Abstract: An intrinsic kinetic modelling for the photo oxidation of oxalic acid (C2O4H4) in a fluidized bed (FB) of a TiO2/quartz sand composite, in a UV-fully illuminated reactor, was attained and correlated with experimental results. A proper solution for the mass balance of the reacting system was achieved by combining the radiation field profile, as obtained in a previous work (Pozzo et al., 2006) and the most recent and updated pathway for the adsorption and photodecomposition of oxalic acid onto TiO2, presented by Mendive and co-workers (Mendive et al., 2006, 2007), and adopted as the basic mechanistic scheme to determine a kinetic expression useful for our modelling purposes.
