Sonochemistry is the application of ultrasound to chemical reactions and processes. The mechanism causing sonochemical effects in liquids is the phenomenon of acoustic cavitation. The chemical effects of ultrasound do not come from a direct interaction with molecular species. Studies have shown that no direct coupling of the acoustic field with chemical species on a molecular level can account for sonochemistry or sonoluminescence. Cavitation the formation, growth, and implosive collapse of

... les irradiated with sound is the impetus for sonochemistry and sonoluminescence. Sonochemistry can be performed by using a bath (usually used for ultrasonic cleaning) or with a high power probe. ______________________________________________________________________________________ 1. Sonochemistry 1.1 Introduction In chemistry, the study of sonochemistry is concerned with understanding the effect of sonic waves and wave properties on chemical systems. The chemical effects of ultrasound do not come from a direct interaction with molecular species. Studies have shown that no direct coupling of the acoustic field with chemical species on a molecular level can account for sonochemistry or sonoluminescence[1,2]. Instead, sonochemistry arises from acoustic cavitation: the formation, growth, and implosive collapse of bubbles in a liquid. This is demonstrated in phenomena such as ultrasound, sonication, sonoluminescence, and sonic cavitation. Sonochemistry is that branch of one, which deals with the study of sonic waves and their properties on chemical systems.
