Abstract

Abstract

Switchable deep-eutectic solvents （SDES） have great application potential in the resource recovery and utilization of organic wastes due to their efficient separation and recovery capabilities. The main classifications of SDES （devied into three types， CO₂/N₂-driven， pH-driven and temperature-driven， based on their driving factors）， their synthesis principles and characterization approaches are outlined， and the driving switchable mechanisms of different SDES based on hydrophilic-hydrophobic transition are elucidated. Also， the effects of the driving factors regulation on the extraction and separation of substances are demonstrated. Then the current application status and advantages of SDES in the organic waste treatment， such as fruit peels， industrial waste liquids， etc.， are summarized. Then the enhanced strategies to improve the extraction efficiency of SDES are illustrated from multiple perspectives， including the optimization of SDES preparation （i.e. composition， molar ratio and volume） and the combination of auxiliary technologies （i.e. ultrasound）. Future researches are suggested to focus on the SDES extraction parameters tailored to different categories of organic wastes， and the improvement of SDES recycling efficiency. This work can provide guidance for their large application in the resource recovery and utilization of organic wastes.
