The review is devoted to extraction solvents of new generation, so called combined solvents, which include ionic liquids, aqueous biphasic systems and eutectic solvents. Most of modern combined solvents are based on organic ionic components. These solvents are associated with high expectations as they are able to provide the environmental safety and green character of extraction, which are priority tasks for the development of chemistry and chemical engineering. For all classes, an overview and a brief history of research are presented; details of structure and properties are discussed; various extraction systems are compared; and typical examples of extraction of metal ions and organic compounds are given. The lack of uniform terminology and difficulties in interpreting the behaviour of some systems, especially eutectic solvents, are outlined. The advantages and drawbacks of new generation extraction solvents and relevant research tasks are summarized.

The bibliography includes 408 references.

该综述致力于新一代萃取溶剂，即所谓的组合溶剂，包括离子液体、水性双相系统和共晶溶剂。大多数现代组合溶剂都基于有机离子成分。这些溶剂具有很高的期望，因为它们能够提供提取的环境安全性和绿色特性，这是化学和化学工程发展的优先任务。对于所有课程，都提供了概述和研究简史；讨论了结构和特性的细节；比较了各种提取系统；并给出了提取金属离​​子和有机化合物的典型实例。概述了在解释某些系统（尤其是共晶溶剂）的行为时缺乏统一的术语和困难。
