Sonochemical degradation of triclosan in water and wastewaterSonochemical degradation of triclosan in water and wastewater Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-09-242008enThe sonochemical degradation of 5 lg l1 triclosan, a priority micro-pollutant, in various environmental samples (seawater, urban runoff and influent domestic wastewater) as well as in model solutions (pure and saline water) was investigated. Experiments were conducted with a horn-type sonicator operating at 80 kHz frequency and a nominal applied power of 135 W, while solid-phase microextraction coupled with gas chromatography–electron capture detector (SPME/GC–ECD) was employed to monitor triclosan degradation. The latter followed pseudo-first order kinetics with the rate constant being (min1): 0.2284 for seawater > 0.1051 for 3.5% NaCl in deionised water > 0.0597 for centrifuged urban runoff 0.0523 for untreated urban runoff > 0.0272 for deionised water > 0.0063 for wastewater influent. SPME/GC–ECD and SPME coupled with gas chromatography–mass spectrometry (SPME/GC–MS) were also used to check for the formation of chlorinated and other toxic by-products; at the conditions in question, the presence of such compounds was not confirmed.http://creativecommons.org/licenses/by/4.0/Ultrasonics sonochemistry155689-6940fcfd5059685c70387000000.pdfChania [Greece]Library of TUC2015-09-24application/pdf307.5 kBfree Elefteria Psillakis Lucia Sanchez-Prado Ruth Barro Maria Llompart Carmen Garcia-Jares Marta Lores Elsevier Experimental
