Abstract:
      With the introduction of concept of green analytical chemistry,the development and utilization of novel green solvents have become a hot topic in contemporary research.Application of green solvents replacing traditional organic solvents in sample pretreatment could reduce the harm to laboratory personnel and the environment.Supramolecular solvents(SUPRASs) have been extensively used for the extraction and enrichment of the target analytes with wide polarity ranges in recent years due to their high-content amphiphilic substances and mild extraction and separation conditions,achieving both extraction and clean-up effects.In this paper,the formation process and basic properties of SUPRASs are introduced.Their advantages in extraction and separation are summarized. The applications of SUPRASs in sample pretreatment are reviewed,including the extraction of target substances by SUPRASs alone or in combination with other pretreatment methods.Combinations of SUPRASs-based extraction with various analytical techniques are also summarized.A systematic overview on the research advances of SUPRASs in sample pretreatment and analytical techniques may provide a theoretical guidance or technical support for their further development and utilization.
