Comparison of route, mechanism and extent of treatment for the degradation of a β-lactam antibiotic by TiO 2 photocatalysis, sonochemistry, electrochemistry and the photo-Fenton system

Treatment technologies for emerging contaminants in water: A review

“…Although the main feature of AOPs is the production of hydroxyl radicals, the type of reaction for hydroxyl radical production and the experimental conditions are highly significant. For example, dicloxacilin degradation has been attempted using UV photolysis [155,163], the decomposition of hydrogen peroxide [156] or ozone [155,[157][158][159] using UV radiation, titanium dioxide photocatalysis [177] and sono-chemical oxidation [175]. A range of studies have reported that dicloxacilin is inert to UV radiation alone, slightly degradable by photocatalysis, but highly sensitive to sono-chemical conditions [175,176].…”

Green Water Treatment for Pharmaceutical Pollution

“…The adsorbent material in combination with titanium dioxide or titania (Ti) showed better results using adsorption combined with photocatalytic activity with low cost, nontoxicity, and high stability in aqueous solution. Nevertheless, the disadvantages of TiO 2 powders are the low surface area (Degussa P25 = 35-45 m 2 g −1 , anatase < m 2 g −1 ); the anatase bandgap of 3.20 eV uses only a small UV fraction of solar light, about 2-3%, with the high cost of the TiO 2 powder separation and recovery from treated wastewater [17,18].…”

Enhanced photocatalytic activity of degrading short chain chlorinated paraffins over reduced graphene oxide/CoFe2O4/Ag nanocomposite

“…Photocatalytic technique, capable of utilizing the clean, safe and renewable solar energy to drive chemical redox reactions, has been considered as one of the promising alternative ways of achieving strong oxidizing ability under mild conditions. [7][8][9][10]. However, no previously reported photocatalytic materials can be referred in terms of SCCPs photocatalytic degradation.…”
