Abstract:
Ultrasonic (US) irradiation, hydrogen peroxide (H(2)O(2)), Fenton's oxidation and the combination of the processes were investigated for destruction and removal of the following trihalomethanes (THMs) compounds from aqueous solutions: CHCl(3), CHBrCl(2), CHBr(2)Cl, CHBr(3), and CHI(3). H(2)O(2) had no significant effect on the THMs sonodegradation. The coupled US and Fenton processes did not affect the CHCl(3), CHBrCl(2), and CHBr(2)Cl sonolysis efficiency. Nevertheless, the sonodegradation of CHBr(3) was enhanced. CHI(3) was degraded by Fenton's oxidation rather than by the US irradiation during the sonication/Fenton treatment. The combination of sonication with H(2)O(2) or Fenton's reagent did not affect the mineralization of the THMs aqueous mixture.
