  • Title: Effect of various reaction parameters on THMs aqueous sonolysis.
    Author: Shemer H, Narkis N.
    Journal: Chemosphere; 2005 Jun; 59(9):1317-21. PubMed ID: 15857643.
    Abstract:
    Ultrasonic irradiation was investigated for destruction of the following THMs: CHCl(3), CHBrCl(2), CHBr(2)Cl, CHBr(3), and CHI(3). The effect of pH, temperature, and the organics initial concentration on the THMs sonodegradation at acoustic frequency of 20 kHz was studied. An increase of the solution temperature resulted in a faster sonodegradation rates. Initial aqueous solution pH, in the range from 3 to 10, was found to have little effect on the degradation of the THMs. The THMs sonolysis efficiency was reduced when the initial organic compounds concentration was increased from 10 mg l(-1) to 300 mg l(-1).
