ULTRASONICALLY INDUCED CAVITATION OF FLUOROCHEMICALS

摘要

A process is described for the treatment of fluorochemicals in an aqueous environment, the process including the steps of (1) ultrasonically inducing cavitation in an aqueous system at a frequency within the range from about 15 kHz to about 1100 kHz, the aqueous system comprising fluorochemicals; and (2) breaking down the fluorochemicals into constituent components by the application of the cavitation. The ultrasonically induced cavitation is performed at a frequency within the range from greater than 200 kHz to about 1100 kHz. The process can be used to facilitate the degradation of any of a variety of fluorochemicals having a carbon chain length of C<SUB>2</SUB> and higher.
