Sulfate radical-based advanced oxidation processes have been of great interest due to the high oxidizing potential of sulfate radical to degrade refractory organic pollutants in aqueous solution. In this study, the degradation of antibiotic TC in aqueous solution by silver-activated persulfate (Na2S2O8) in the presence of ultrasound irradiation under various conditions has been investigated. The effects of several parameters such as Ag2SO4, Na2S2O8 concentration, temperature, ultrasonic (US) power, initial TC concentration and initial pH on the degradation of TC were investigated. More than 83% of TC removal was achieved within 120 min under optimal conditions. The optimum operational conditions were found to be as follows: Ag2SO4 dosage 3.5 mmol\/L, Na2S2O8 concentration 70 mmol\/L, reaction temperature 25 \u00b0C, US power 120 W, initial TC concentration 50 mg\/L, pH 3.0 and contact time 120 min. The degradation of TC in the persulfate\/Ag+\/US process followed the pseudo-first-order kinetics.<\/jats:p>","DOI":"10.2166\/wst.2015.607","type":"journal-article","created":{"date-parts":[[2015,12,3]],"date-time":"2015-12-03T18:56:34Z","timestamp":1449168994000},"page":"1293-1300","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":41,"title":["Enhanced
