Abstract：Removal of butyl acetate (BA) from model wastewater (0.40%, j) through solvent sublation method into n-nonane was studied, and n-nonane was used as the upper collecting solvent. The effects of operation variables, such as contact time, gas flow rate, volume ratio of n-nonane to wastewater and the bubble diameter, on the removal efficiency were explored, among which the effect of bubble size was emphasized. The results indicated that the final separation efficiency reached as high as 60% with a electrolysis gas flow rate of 1.67 mL/min and bubble diameter of 0.2 mm, when the gas flow rate was 20 mL/min and the diameter of bubble was 0.6 mm, the separation efficiency also could achieve 60%, both with the volume ratio of n-nonane to wastewater 1:25. But the separation time, total gas volume and secondary pollution caused by n-nonane had great difference.
