Description

'The primary objective of this research project is to acquire a deeper fundamental knowledge of acoustic cavitation and cavitation chemistry, and in doing so, to ascertain how ultrasonic irradiation can be more effectively applied to environmental problems. The primary objective will be accomplished by examining numerous aspects of sonochemical systems and acoustic cavitation. During the course of the project, the research group will investigate the significance of physical variables during sonolysis, sonochemical kinetics and reactive intermediates, and the behavior of heterogeneous (solid/liquid) systems. An additional component of the project includes utilizing various techniques to image cavitation bubble cloud development. This ... continued below

The primary objective will be accomplished by examining numerous aspects of sonochemical systems and acoustic cavitation. During the course of the project, the research group will investigate the significance of physical variables during sonolysis, sonochemical kinetics and reactive intermediates, and the behavior of heterogeneous (solid/liquid) systems. An additional component of the project includes utilizing various techniques to image cavitation bubble cloud development. This report summarizes results after 2 years of a 3 year investigation. Four on-going projects will be described. The first project is the destruction of polychlorinated biphenyls at multiple ultrasonic frequencies. The second project is a comprehensive study of how ultrasonic frequency influences sonochemical reaction rates; in particular, hydrogen peroxide formation. Finally, the sonochemical destruction of the pesticides dichlorvos (at 500 kHz) and carbofuran (parallel-plate reactor) has been examined.'
