Environmental pollution is a recognized issue of major concern since a wide range of contaminants has been found in aquatic environment at ng L −1 to μg L −1 levels.In the year 2000, a strategy was defined to identify the priority substances concerning aquatic ecosystems, followed by the definition of environmental quality standards (EQS) in 2008. Recently it was launched the Directive 2013/39/EU that updates the water framework policy highlighting the need to develop new water treatment technologies to deal with such problem. This review summarizes the data published in the last decade regarding the application of advanced oxidation processes (AOPs) to treat priority compounds and certain other pollutants defined in this Directive, excluding the inorganic species (cadmium, lead, mercury, nickel and their derivatives).The Directive 2013/39/EU includes several pesticides

“…The hydroxyl radical is the second strongest oxidant with an oxidation potential at 2.80 V. It is effective at destroying organic pollutants rapidly with second-order rate constants, usually in the range of 10 9 -10 10 M -1 s -1 , and non-selectively with nearly all electron-rich organic compounds (26), such as hydrocarbons (23,27), organic dyes (28,29), antibiotics (30,31), pesticides (32,33), landfill leachates (34,35), explosives (36)(37)(38), phenols (39,40), and microbial contaminants (17,41). Meanwhile, nanocatalysis is one of many practical applications of nanotechnology.…”

The lack of clean and safe drinking water is responsible for more deaths than war, terrorism and weapons of mass destruction combined. This suggests contaminated water poses a significant threat to human health and welfare. In addition, standard water disinfection approaches such as sedimentation, filtration, and chemical or biological degradation are not fully capable of destroying emerging contaminants (e.g. pesticides, pharmaceutical waste products) or certain types of bacteria (e.g. Cryptosporidium parvum). Nanomaterials and nanotechnology based devices can potentially be employed to solve the challenges posed by various contaminants and

“…Advanced Oxidation Processes (AOPs) are physicochemical techniques (De la Cruz et al, 2013Rubio-Clemente et al, 2014), which have been applied to treat organic pollutants in both drinking water and wastewater (De la Cruz et al, 2013;Giraldo et al, 2010;Guzman-Duque et al, 2011;Velegraki and Mantzavinos, 2015). AOPs are characterized by the formation of oxidative species, mainly the hydroxyl radical ( OH), which degrades organic compounds with high reaction rates (Glaze et al, 1987).…”

a b s t r a c tTo provide new insights toward the selection of the most suitable AOP for isoxazolyl penicillins elimination, the degradation of dicloxacillin, a isoxazolyl penicillin model, was studied using different advanced oxidation processes (AOPs): ultrasound (US), photo-Fenton (UV/H 2 O 2 /Fe 2þ ) and TiO 2 photocatalysis (UV/TiO 2 ). Although all processes achieved total removal of the antibiotic and antimicrobial activity, and increased the biodegradability level of the solutions, significant differences concerning the mineralization extend, the pH of the solution, the pollutant concentration and the chemical nature of additives were found. UV/TiO 2 reached almost complete mineralization; while~10% mineralization was obtained for UV/H 2 O 2 /Fe 2þ and practically zero for US. Effect of initial pH, mineral natural water and the presence of organic (glucose, 2-propanol and oxalic acid) were then investigated. UV/H 2 O 2 /Fe 2þ and US processes were improved in acidic media, while natural pH favored UV/TiO 2 system. According to both the nature of the added organic compound and the process, inhibition, no effect or enhancement of the degradation rate was observed. The degradation in natural mineral water showed contrasting results according to the antibiotic concentration: US process was enhanced at low concentration of dicloxacillin followed by detrimental effects at high substrate concentrations. A contrary effect was observed during photo-Fenton, while UV/TiO 2 was inhibited in all of cases. Finally, a schema illustrating the enhancement or inhibiting effects of water matrix is proposed as a tool for selecting the best process for isoxazolyl penicillins degradation.
