New absorbents composed of diethylene glycol monobutyl ether (DGBE), paraffin oil, and ionic liquids (ILs) were prepared for the removal of gaseous acetone. Three ILs, namely, [bmim][PF 6 ], [bmim][BF 4 ], and [bmim][Ac], were used to regulate the absorption performance. Different paraffin oil mass fractions and IL mass fractions were applied to determine the right formula with suitable physical properties and absorption performance. The Henry coefficients of acetone in the absorbents were measured to evaluate the influence of absorbent composition on the absorption capacity. The removal performances of these absorbents were investigated in a bubbling bottle to evaluate the combined impact of Henry coefficient and physical properties.
