Destruction of Polycyclic Aromatic Hydrocarbons with Ultrasound

Abstract
Dilute ethanol-water solutions of a few polycyclic aromatic hydrocarbons, a dioxin, and neat chlorinated solvents were sonicated and then characterized by UV-visible absorption spectrophotometry and laser excited Shpol'skii spectrometry. The results indicate that all the compounds were destroyed on sonication leaving a carbonaceous residue.
