Application of deep eutectic solvent extraction in eco-geological sample analysis

新型绿色溶剂的开发和利用是当前的研究热点。将绿色溶剂替代传统溶剂用于生态地质样品前处理过程,可以减少对实验人员及环境的危害。深共晶溶剂因其具有可生物降解性、低环境影响、低成本和易于合成等优点,逐渐被应用于生态地质样品中分析物的提取和分离。文章在介绍深共晶溶剂的概念、制备方法和主要理化特性的基础上,综述了该技术在水、土壤和生物样品检测中的最新研究进展,并对其应用前景进行了展望,认为深共晶溶剂是一类有望替代传统有毒有害溶剂的新型绿色溶剂,但仍需要解决其高黏度的缺点,同时要加强提取机理研究和与多种检测方法联用技术的研究。

The development and utilization of innovative green solvents is currently a hot topic of research.Substituting conventional solvents with environment friendly alternatives in the pretreatment of ecological geological samples can effectively mitigate potential risks to both researchers and the environment.Deep eutectic solvents(DESs)have garnered increasing attention due to their biodegradability,minimal environmental impact,cost-effectiveness and facile synthesis,rendering them suitable for extraction and separation in eco-geological sample analysis.This paper comprehensively overviews the deep eutectic solvents(DESs)from the perspectives of its conceptual framework,preparation methodologies,and essential physicochemical properties.Additionally,it summarizes latest research advances on applying DES technology to water quality assessment,soil analysis,and biological sample characterization with the discussion of its prospects.As a new type of green solvent,DESs offers a promising alternative to replace conventional toxic solvents;however,it is crucial to address challenges related to high viscosity along with further investigation in extraction mechanisms and integration with various detection techniques.
