Degradation Kinetic of Oxytetracycline Antibiotic inside UV Reactor in the Presence of H₂O₂

Abstract:

– Oxytetracycline (OTC), a widely used of veterinary antibiotic, was degraded inside a UV/H₂O₂ system. Kinetic study was conducted at 30°C of temperature and pH 6.37, as suggested by the previous optimization experiment. About 250, 375 and 500 ppm initial OTC concentration were used for the kinetic studies, at H₂O₂ concentration of 0.116 M. The experimental data were plotted against the pseudo zero-th, first and second order of kinetic. Based on regression coefficient value, the data was well fitted with the pseudo first order of kinetic. The calculated value of k_obs was 0.181 min^-1.
