abstract
A bimolecular kinetic model is proposed for the liquid phase ozonation of organic components, incorporating direct and indirect ozonation by means of bimolecular reaction steps. One of the advantages of this model is that all radicals, present in the liquid phase, are lumped into one concentration, reducing the number of kinetic parameters. The main objective of this paper is to determine the degradation kinetics of ciprofloxacin (CIP), as model component for the class of fluoroquinolones, in order to validate the proposed kinetic model on available experimental data, obtained in a lab scale bubble column reactor. Additionally, different reactor models such as a continuous stirred tank reactor (CSTR) and a plug flow reactor (PFR) are compared in the description of the experimental data. A realistic mass transfer coefficient for ozone from the gas to the liquid phase of 1.65 10(-3) s(-1) is obtained and the estimated bimolecular reaction rate coefficients are within the range, described by literature. The calculated responses are in good agreement with the experimental results. Knowledge of both the reaction kinetics and the corresponding reactor model is a promising tool to simulate and optimize ozonation reactor configurations.
