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.
