Title: Degradation and removal methods of antibiotics from aqueous matrices - A review
Issue Date: 2011
Abstract: Over the past few years, antibiotics have been considered emerging pollutants due to their continuousinput and persistence in the aquatic ecosystem even at low concentrations. They have been detectedworldwide in environmental matrices, indicating their ineffective removal from water and wastewaterusing conventional treatment methods. To prevent this contamination, several processes to degrade/remove antibiotics have been studied. This review addresses the current state of knowledge concerningthe input sources, occurrence and mainly the degradation and removal processes applied to a specificclass of micropollutants, the antibiotics. In this paper, different remediation techniques were evaluatedand compared, such as conventional techniques (biological processes, filtration, coagulation, flocculationand sedimentation), advanced oxidation processes (AOPs), adsorption, membrane processes andcombined methods. In this study, it was found that ozonation, Fenton/photo-Fenton and semiconductorphotocatalysis were the most tested methodologies. Combined processes seem to be the best solution forthe treatment of effluents containing antibiotics, especially those using renewable energy and byproductsmaterials.
