ABSTRACT: In this work, the degradation of low-concentration butyl acetate was performed in a micro-nano bubble
device via the cavitation effect. The degradation efficiency of this process was investigated for different butyl acetate
concentrations. The experimental results showed that with a butyl acetate concentration of 186.5 mg/m3
, the
degradation efficiency of butyl acetate was 77.6%. Gas chromatography-mass spectrometry was used to identify the
intermediate products generated during different treatment periods under varying initial concentrations. Based on the
product analysis, the degradation reaction and pathway were speculated. All the results showed that the major reaction
pathway of butyl acetate degradation was the initial production of low-carbon ester, which was then decomposed into
butyl alcohol and acetone compounds. This study provides a deeper understanding of the degradation of butyl acetate
by micro-nano bubbles and the mechanism of degradation.
