The recent progress of solvent sublation

Solvent sublation is a kind of adsorptive bubble separation technique in which the surface-active (or hydrophobic) compounds in aqueous phase are adsorbed on the bubble surfaces of an ascending gas stream and then collected in an organic layer placed on top of the aqueous phase. The technique has many advantages, such as high separation efficiency, high concentration coefficient, low dosage of organic solvent, soft separation process, and simple operation. Thus, this technique has been widely applied in many fields. The present article reviews solvent sublation's theoretical research and some applications in the last 10 years, and gives the development trend in the future.
