Abstract:		"As an eco-friendly technology, micro-nano bubbles have gained extensive attention due to their excellent properties. We carried out the experiments to investigate the degradation performance of micro-nano bubbles on ethyl acetate at ambient temperature and pressure. The effects were deeply analyzed by studying the treatment time, initial concentration, and mixed components on ethyl acetate. Treatment time at 30 min had the best results, with a removal efficiency of 86.07 % and a degradation rate of 0.340 +/- 0.021 min(-1). With the increase of the initial ethyl acetate concentration, the degradation extent first increased and then decreased. The best efficiency of 94.61% and the maximum reaction rate of 8.79x10(-3) min(-1) were achieved at an initial concentration of 265.6 mg/m(3). In addition, ethyl acetate degradation was inhibited by the presence of butyl acetate, and removal efficiency of mixed components was lower than that of single components. The GC-MS results showed that possible intermediates, such as ethanol and acetone, were produced during the decomposition process, which was expected to eventually decompose into CO(2) and H(2)O as the reaction progresses. This work presents a new method for the degradation of ethyl acetate and provides valuable information for the degradation of organic matter by micro-nano bubbles"
