Abstract

Recent studies have shown that high power ultrasound can be used to remove organic contamination from soils and sediments. This paper presents a study of the destruction of tetrachloronaphthalene in sand. Ultrasonic treatment of the samples was performed using a 12.5 mm tip diameter Misonix horn, which could deliver approximately 160W of power. After 2 minutes of sonication, the concentration of tetrachloronaphthalene in sand was reduced by 90%. No significant breakdown products were detected. The underlying physics of the process is explained.
