5. Limitations of sonochemistry

5.1 Reproducibility

One of the main difficulties associated with the use of ultrasound is the reproducibility of results. Numerous parameters have to be taken into account during an experiment, such as the geometry of the reactor used, the type of probe and the medium through which the ultrasonic wave passes. The concentration of dissolved gas can also affect cavitation. To compare different experiments carried out under ultrasound, it is necessary to use the same equipment for each one and to describe the experimental conditions in great detail.
