Basic Study on Oxidation of Organic Compounds by Cavitating Submerged Water Jets

Abstract

Cavitating submerged water jets have recently attracted attention as an efficient way of oxidation of harmful organic compounds. In this study, we carried out systematic experiments using a small cavitating jet apparatus for investigating the oxidation effect of a cavitating jet and influences of various conditions. The oxidation efficiency was measured for four different compounds, 1,4-dichlorobenzene, biphenyl, dibenzofuran and dibenzo-p-dioxin, and products of the reaction were identified using a gas chromatograph-mass spectrometer. The influence of OH-radical was also investigated by adding t-butyl alcohol as scavenger.
