Trihalomethanes aqueous solutions sono-oxidation
چکیده انگلیسی

Ultrasonic (US) irradiation, hydrogen peroxide (H2O2), Fenton's oxidation and the combination of the processes were investigated for destruction and removal of the following trihalomethanes (THMs) compounds from aqueous solutions: CHCl3, CHBrCl2, CHBr2Cl, CHBr3, and CHI3. H2O2 had no significant effect on the THMs sonodegradation. The coupled US and Fenton processes did not affect the CHCl3, CHBrCl2, and CHBr2Cl sonolysis efficiency. Nevertheless, the sonodegradation of CHBr3 was enhanced. CHI3 was degraded by Fenton's oxidation rather than by the US irradiation during the sonication/Fenton treatment. The combination of sonication with H2O2 or Fenton's reagent did not affect the mineralization of the THMs aqueous mixture.
