摘　　要：溶剂浮选是一种被气泡传质效应强化的液-液萃取技术,具有高分离效率、高富集系数、传质温和、低有机溶剂消耗、操作简单等优点,广泛应用于仪器分析的样品前处理、水体中有机污染物的分离富集、天然产物中活性物质分离等领域。本文比较全面地综述了溶剂浮选技术的通用模式、分离参数、应用现状和理论研究进展;在此基础上,重点介绍了近些年溶剂浮选领域出现的一些新分离模式和应用领域:新的分离模式主要是"双水相浮选"和"气浮络合萃取",新的应用领域主要是样品前处理技术的新应用以及对天然产物提取液中活性物质的分离富集。Solvent sublation is a special liquid-liquid extraction, bubble mass transfer. Solvent sublation has many advantages, which is greatly strengthened by the effect of 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.
