摘  要:可切换低共熔溶剂(SDES)因其高效分离回收的能力,在有机废弃物资源化处理等领域具有较大的应用潜力。概述了SDES的主要分类(基于不同驱动因子可分为CO_(2)/N_(2)驱动型、pH驱动型和温度驱动型)、合成原理和表征手段,阐明了不同SDES基于亲疏水性转变实现切换的驱动机制;分别阐明了3种驱动因子的调控对物质提取分离效果的影响。在此基础上,总结了SDES在果皮、工业废液等有机废弃物资源化处理中的应用现状及优势,并从SDES制备的优化(组成、摩尔比和体积)与辅助技术的结合(如超声辅助)等多角度阐释了提升SDES提取效果的强化策略。最后,针对不同废弃物的SDES提取参数优化确定以及如何提高SDES回收利用等方面进行了展望,可为其在有机废弃物资源化方面的应用研究提供参考。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,CO_(2)/N_(2)-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 hydrophilichydrophobic 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.
