Solvent sublation is a special liquid-liquid extraction, which is greatly strengthened by the effect of bubble mass transfer. Solvent sublation has many advantages, such as high separation efficiency, high concentration coefficient, soft separation process, low dosage of organic solvent and simple operation. Thus, this technique has been widely applied in sample pretreatment of instrumental analysis, separation and concentration of organic pollutants in water sample, separation of active components in natural products and so on. The present article mainly reviews the recent progress of theory and application research in solvent sublation. Furthermore, several novel separation modes (aqueous two-phase extraction and flotation complexation extraction) and new application fields (sample pretreatment and separation of active components from extract of natural products) are also introduced in detail.
