“…The photo-Fenton treatment of endosulfan in a pilot solar plant, using 8 mM of H2O2 and 0.18 mM of Fe 2+ , increased the biodegradability of the endosulfan-contaminated effluent by 50% after 90 min (Kenfack et al, 2009). The photo-Fenton process of lindane using UV-vis radiation led to a 95% TOC reduction in 2 h (Nitoi et al, 2013). Photo-Fenton was effective in the degradation and mineralization of alachlor, atrazine, chlorfenvinphos, diuron, isoproturon and pentachlorophenol in a solar pilot-plant with three CPCs under natural sunlight (Rubio et al, 2006).…”

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

“…Once supported by UV radiation it provides nearly perfect decarbonisation and dechlorination (Khan et al 2015) due to strong role of SO 4 2-radical in slightly acidic environment (pH about 5.8) (Khan et al 2016). Other methods include photodegradation with photo-Fenton reaction (Nitoi et al 2013;Antonaraki et al 2010;Senthilnathan and Philip 2010) assuring total organic carbon removal within 2 h and some biodegradation processes including oxidation by fungi (Guillén-Jiménez et al 2012;Rigas et al 2010) or bacteria using it as a carbon source (Pesce and Wunderlin 2004;Saez et al 2012Saez et al , 2014. But not only simple microorganisms can cope with themalso demosponges were found to be capable of its biodegradation (Aresta et al 2015).…”

Persistent organic pollutants are a serious problem to the environment due to their toxicity to both fauna and flora. Extremely resistant to biodegradation and prone to transfer through long distances via atmosphere can contaminate almost any place in the planet. They tend to bioaccumulate in fat tissue due to their lipophilicity and seriously affect poisoned organism's nervous, hepatic, reproductive or hormonal system. Since 2009, due to the Stockholm convention on persistent organic pollutants production and utilisation of certain halogenated pesticides has been prohibited. This group includes hexachlorocyclohexane, chlordecone (kepone) and pentachlorobenzene. All of these chloropesticides pose a serious threat to environment, and careful control of their production and release to the environment is required. This paper is a review of physical and chemical properties as well as sources in environment, impact on animal organisms, methods of degradation of most broadly used chlorinated persistent organic pollutants and suggestions concerning their utilisation.

Online spectrophotometric technology was used to monitor the Fenton oxidation of the model dye Reactive Red 6B (RR6B) in an aqueous solution. The results showed that online monitoring technology was well equipped to record detailed information during the Fenton process. RR6B was successfully decomposed by Fenton oxidation and it was determined that optimal experimental conditions yielded nearly 100% dye removal to be 3.5 3 10 25 M ferrous ion, 2.5 3 10 23 M hydrogen peroxide and 3.85 pH. Both firstorder and Behnajady-Modirshahla-Ghanbery kinetics models described the Fenton process well with correlation coefficients above 0.99. The instant concentration of hydroxyl radicals and the reaction rate at different conditions were also calculated based on the above two models.
