Monitoring the sonochemical field: A critical review of chemical dosimetry methods

Sonochemistry is a fascinating field that has drawn considerable interest from researchers across different disciplines. One of the key challenges in this field is the accurate characterization of the sonochemical field, which is crucial for understanding the underlying mechanisms and optimizing the process. To address this challenge, researchers have developed various monitoring methods that allow them to measure key parameters such as the intensity, frequency, and distribution of acoustic waves in the sonoreactor. In this review, we focus on the chemical dosimetry techniques that are commonly used for sonochemical monitoring. These techniques have been extensively studied in the literature and are known for their reliability and accuracy. However, as we will see, the performance of these techniques can vary depending on the chemical nature of the probing species and the experimental conditions, highlighting the need for a careful selection and calibration of the monitoring method. We begin by discussing the principles of chemical dosimetry in sonochemistry and how these methods can be used to measure key sono‐acoustic parameters. We then provide a detailed analysis of the various dosimetry techniques, including their advantages, limitations, and applicability under different operating conditions. In summary, our review serves as a valuable resource for researchers seeking to optimize their sonochemical experiments and contribute to the advancement of this fascinating field.
