Abstract:	Abstract The main aim of the present research, as the first study, was coupling of hydrogen peroxide (H₂O₂), ferrous ions (Fe²⁺) and UV irradiation in a photo-Fenton system to degradation two antibiotics (e.g. meropenem and ceftriaxone) from aqueous solution. The tests were carried out at different experimental conditions namely solution pH, iron dosages, H₂O₂ concentrations, UV light intensities, temperatures, and initial antibiotic concentrations. The degradation rates of 99 and 96.2% were observed for respectively meropenem and ceftriaxone during 60?min treatment. Biodegradability tests illustrated that photo-Fenton system has a high performance in removing organic compounds and biodegradability enhanced remarkably after treatment.
