Abstract
Ultrasonic degradation of halomethane mixtures, with very low initial concentration in chlorinated drinking water was investigated. It was observed that the removal efficiencies of four halomethanes after 1 h ultrasonic irradiation followed the increasing order: CHCl3 < CHBr2Cl < CHBrCl2 < CCl4 and the degradation reactions of the halomethanes were well described by the pseudo-first-order kinetics model. Molecular polarity was found to be an important factor controlling the sonodegradation of halomethane mixtures. Increasing acoustic intensity enhanced the removal of halomethanes in chlorinated drinking water. In addition, ultrasonic irradiation led to a slightly decrease of pH and TOC of chlorinated drinking water.
