Nowadays, the occurrence of pharmaceuticals in the environment and the continuous augmentation of their concentrations in natural water sources have become a major environmental issue demanding the development of powerful technologies aiming to achieve their effective destruction (Kümmerer, 2009a and Rivera-Utrilla et?al., 2013). It has been demonstrated that these substances along with their Hoechst 34580
products represent a toxicological risk for both aquatic ecosystems and living beings, some of them having been classified as endocrine disrupting compounds (Khetan and Collins, 2007, Fatta-Kassinos et?al., 2011 and Laurencé et?al., 2014). Because of their high anti-bacterial resistance, antibiotics
most commonly drugs found in the aquatic environment (El-Ghenymy et?al., 2013a, Kümmerer, 2009b and Thiele-Bruhn and Beck, 2005). Among them, sulfamethazine (SMT) is widely used in human and veterinary medicine and it has been detected in surface waters and sewage treatment plants (García-Galán et?al., 2011, Jia et?al., 2011 and Li and Zhang, 2011). Previous works have reported the successful incineration of this drug by means of classical EF process using a BDD anode (El-Ghenymy et al., 2013b). This antimicrobial drug was thereby chosen as a model for studying the application of pyrite as an alternative catalyst for EF process.
