“…4-tert-octylphenol degradation was tested using a TiO2 precursor sol coated on the inner wall of a photoreactor at λ = 254 nm (Wu et al, 2012) as well as a NaBiO3 photocatalyst under visible radiation (Chang et al, 2010), in both cases up to 90% of the pol-lutant removal being obtained. Chlorpyrifos, cypermethrin and chlorothalonil were removed after 30 min in an experiment using TiO2, UV radiation (λ = 365 nm) and H2O2 (Affam and Chaudhuri, 2013). Different pesticides (individually and as mixture) were studied in various matrices including laboratory grade water, surface water and groundwater, the decreasing order of degradation being observed: diuron and chlorfenvinphos N alachlor, pentachlorophenol and atrazine ≫ isoproturon (Sanches et al, 2010).…”

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

“…Many studies have demonstrated the degradation of organic pollutants such as phenol, chlorinated hydrocarbons, chlorophenols, insecticides, dyes and others, using the photocatalysis process in the presence of TiO 2 under solar radiation [4][5][6]. However, due to the high energy required for activation of TiO 2 for generating the hydroxyl radicals (band gap equal to 3.2 eV), the yield of the process is limited by the absorption of radiation up to 385 nm, which corresponds to only about 5% of the solar spectrum [7,8].…”

A B S T R A C TPure (Bi 12 TiO 20 ) and La-and Pb-doped (Bi 12Àx La x TiO 20 e Bi 12Àx Pb x TiO 20 , with "x" up to 1.50) bismuth titanates were prepared by the oxidant peroxide method (OPM) and used for photodegradation of rhodamine b (RhB). The synthesized materials samples were characterized by X-ray diffraction (XRD), UV-vis diffuse reflectance spectra (DRS), X-ray photoluminescence (PL) spectroscopy, scanning electron microscopy (SEM), X-ray fluorescence (XRF) and N 2 physical adsorption. Rietveld refinements showed samples consisting mainly of sillenite structure with small amounts of a perovskite secondary phase in the La-and Pb-doped materials. The photocatalytic properties of all materials were evaluated by the discoloration of RhB solution under ultraviolet (UV) and visible irradiation, where the bismuth titanate obtained by the OPM route showed higher photocatalytic activity than the commercial TiO 2 . Furthermore, it was observed that the insertion of different ions in the bismuth titanate structure changes the band gap energy in different ways, which consequently altered the photocatalytic activities of the materials.
