ABSTRACT
Cavitation caused by ultrasound leads to physical and chemical effects. The physical effects are related to microstreaming and mixing, which accelerate cleaning, extraction, polymer degradation, and other processes. The chemical effects are attributed to the production of OH and H radicals that can generate or in¢uence some chemical reactions. It is well known that the intensity of these physical and chemical effects depends on various factors, such as the physical properties of media, emitted frequency, and intensity. Therefore, it is not easy to reproduce and compare the experimental results reported by different researchers. This might slow down the progress of industrial application in sonochemistry.
