| Research Abstract |
The separation and decomposition of volatile organic compound in water by using ultrasonic atomization and cavitation were investigated. The separation of organic compound from water was subjected by the concentration of organic compound at liquid surface. With increasing ultrasonic frequency, the atomization rate decreased and the droplet number increased. Dual pulse ultrasound enhances 1.6 times more reaction rate than normal ultrasound. This system can efficiently separate and decompose organic compound in water.
