As a large portion of the administered doses is excreted from medicine applications, agriculture and the pharmaceutical industry, a substantial amount of antibiotics (e.g. tetracyclines, sulfonamides, and fluoroquinolones) is released to the environment. For example, fluoroquinolones are a class of antibacterial compounds used extensively in both human and veterinary medicine and have a total consumption of approximately 44 million kilograms every year world-wide; fluoroquinolones exist in hospital wastewaters (60-120000 ng/L), wastewater treatment plant effluents (2-580 ng/L) and surface waters (5-1300 ng/L). However, antibiotic in the environment cannot be effectively removed or degraded by sewage treatment processes due to its stable chemical structures. It has been demonstrated that antibiotics residues in the environment can result in the evolution of novel antibiotic-resistant bacteria that ultimately pose a threat to the aquatic ecosystem and human health, such as human organ lesions and increased bacterial resistance. Hence, it is significant and essential to remove antibiotics efficiently from water to reduce environmental and ecological risks.
In this special issue, review articles, research papers, and short communications will focus on the recent advances in degradation of antibiotics via the advanced oxidation processes (AOPs), including photocatalysis, Fenton, Fenton-like, UV/H2O2, and O3 catalytic ozonation.
