环境超声化学

Environmental Sonochemistry

环境超声化学利用超声空化效应分解液相污染物，属于高级氧化过程。介绍了环境超声化学的基本原理，包括超声空化理论、超声降解环境污染物机理及生成自由基反应。综述了近年来环境超声化学在污染物净化中的应用，对存在问题和发展趋势提出了见解。

Environmental sonochemistry, plication of ultrasound to induce cavitation to as an advanced oxidation process, involves the ap- destroy or accelerate the destruction of liquid-- phase contaminants. This paper introduces the principle of environmental sonochemistry, inclu- ding ultrasonic cavitation theory, mechanism of the ultrasonic degradation of contaminants and the generation of reactive radicals during sonolysis. Moreover, it reviews the progress in treat- ment of pollutants by using environmental sonochemistry in recent years. In addition, existing problems and future study directions are discussed.
