AbstractNitrobenzene, isophorone, 2,6‐dinitrotoluene and 2,4‐dinitrotoluene were removed from aqueous solution by solvent sublation. The separation efficiencies of three solvents (4‐methyl‐2‐pentanone, 1‐octanol and paraffin oil) as the overlaying layer were compared. The rate of separation of these organic pollutants by solvent sublation depends strongly on the size of air bubbles, which is affected by the overlaying solvent, and concentrations of sodium dodecyl sulfate (NDS), inorganic and polar org
