Several factors affecting sonochemical yield

Sound cavitation is the driving force of sonochemical reactions. Investigation on sonochemical yield is useful in application of sonochemistry. Numerous experimental results show that the quantity of sonochemical yield mostly depends on the type of sonochemical reactors and operating parameters under certain physical and chemical conditions. This paper analyzes parameters of the medium and the sound waves in the reactor that influence the cavitation yield. The parameters include viscidity and compressibility of the medium, geometry of the reactor, sound intensity and frequency, etc. Suitable values of frequency, sound pressure and energy density should be chosen to produce maximum yield. Inter-relations of the parameters are studied based on cavity clusters. When the collapse pressure value is greater than the cavitation threshold, the sonochemical yield will be higher if the cavity cluster has a wider territory. Finally, urgent problems and direction of studies in this field are discussed.
