“…FQs are widely diffused in environmental aqueous matrices at concentrations in the range of nanograms/micrograms per liter (Speltini et al 2011. They are photosensitive molecules, and their photochemistry has been widely investigated (Albini and Monti 2003;Ge et al 2010;Sturini et al 2012a, b;Sunderland et al 1999;Tan et al 2013;Wei et al 2013;Yan and Song 2014). The choice of such xenobiotics as a benchmark is due to the fact that their photodegradation paths depend on structure and experimental conditions; hence, this could be informative for rationalizing the behavior of new photocatalysts.…”

This is the first report on the photodegradation of ofloxacin under simulated solar light and in actual environmental matrices in the presence of a g-CN suspension. The catalyst, prepared from the polymerization of dicyandiamide (650 °C, reaction yield 60%), was characterized by means of powder X-ray diffraction (PXRD), UV-vis diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM), and BET surface area measurements. The experiments were carried out in a lab-scale batch reactor at concentrations in the range of micrograms/milligrams per liter. The course of the reaction was monitored by high-pressure liquid chromatography with UV-vis and fluorescence detectors. The g-CN-promoted photodegradation occurred at a rate 10 times faster than the direct photolysis and obeyed a first-order kinetics; in addition, the photodegradation kinetics of sonicated g-CN resulted to be of the same order of that caused by P25 TiO. Finally, the photochemical paths and the photoproducts have been identified and compared to those obtained by using P25 TiO. From the results of this study, it can be concluded that g-CN is a very attractive photocatalyst compared to P25 TiO in view of its ease of preparation, low cost, excellent oxidizing properties, large fraction of solar radiation absorbed, and intrinsically layered structure.

“…According to the theory, the more suitable model is that which results higher coefficients of determination (R 2 ). Thus the adsorption of CFHCl on SO 3 H-SBA-15 is followed the pseudo-second-order model indicate that chemisorption might be the predominant adsorption interaction which is attributed to the electrostatic interaction between SO 3 H-SBA-15 and CFHCl [14,33].…”

“…Additionally, the first four technologies are also challenged by easily influenced by the surrounding environment, generating secondary pollution, and needing complex equipment. Adsorption removal investigations featured with cost-effective, flexibility, simple design, easy operation and insensitivity to toxic pollutants, have been conducted on carbon materials [11,12], metal oxide [13], polymers [14], zeolites [15,16]. However, all of the above mentioned adsorbents are limited by the pore size exclusion as most of antibiotics molecules are in the range of nanometers, or lack of functionalities which is important for the adsorption of antibiotics possessing complex molecular formula and different functional groups.…”

“…For example, a MIP was used for the selective removal of single contaminants, such as 17b-estradiol at trace concentration (Ko1 et al 2011;Le Noir et al 2007), diclofenac from contaminated water (Dai et al 2011), perfluorooctane sulfonate from aqueous solution (Yu et al 2008), 2,4-dichlorophenol from contaminated water (Li et al 2009b), 2,4-dichlorophenoxyacetic acid from water (Han et al 2010) and nonylphenol from aqueous solution (Pan et al 2013). MIPs also have been used for the selective removal of several contaminants of the same family, such as phenolic estrogens from different water sources (Lin et al 2008), polycyclic aromatic hydrocarbons from contaminated water (Krupadam et al 2010), endocrine-disrupting contaminants from aqueous effluents (Fernández-Á lvarez et al 2009), estrogenic compounds and water-soluble acid dyes from a water environment (Zhang and Hu 2008;Luo et al 2011) and more recently, fluoroquinolone antibiotics from aqueous solution (Tan et al 2013). Liu et al (2014) have used a double-template MIP on the surface of carbon microspheres for the selective removal of benzothiophene and dibenzothiophene from gasoline.…”

The efficiency and the reuse of a bisphenol-A molecularly imprinted polymer (BPA-MIP) were evaluated for the selective removal of several phenolic compounds and phenoxyacid herbicides from environmental water samples. The proper sorption and selective recognition ability of the MIP were studied in aqueous solution by the batch equilibrium technique. Furthermore, removal of the analytes studied by the MIP was carried out from river, tap and ground waters, and different factors, such as the sample volume, the solution pH or the analyte concentration in the sample, were studied. Results obtained indicated a rapid sorption of analytes by the MIP, being the sorption dependent on the concentration of analyte in the solution. The MIP showed an excellent affinity toward phenolic compounds and phenoxyacid herbicides, and removal efficiencies of over 70 % were achieved in aqueous solution. Removal efficiency was not affected by the pH or by the water type, although it was affected by the volume of water especially for nitrophenols when amounts in solution were C1 mg. Removal efficiencies recorded by the MIP for the highest volume of water assayed were around 20 % higher than those obtained with traditional sorbents for chlorophenols and bisphenols, and similar removal efficiencies were obtained for phenoxyacid herbicides. The use of the MIP provided a selective, simple, reliable and viable solution for removing these compounds from water, and it could be re-used at least 20 times without losing any removal efficiency.
