In this work, the effect of six variables: sustrate concentration, initial pH, peroxide/substrate molar ratio, bubbling rate, recirculation rate, and irradiation wavelength on the photocatalytic degradation of chloramphenicol (CAP) using TiO2 immobilized on glass Raschig rings was studied. The analysis was planned as a fractional factorial design, in order to determine the best affordable experimental conditions to diminish the energetic cost of treatment of this antibiotic, used for the plague treatment in salmon allevines from fish cultures in the southern zone of Chile. For a given sustrate concentration, the best results were obtained at 360 nm irradiation, adding H2O2 and O2 at the higher pH. © 2007 Science & Technology Network, Inc.
