摘要

近年来，随着经济社会的快速发展，废水中有价金属离子的污染已成为环境可持续性面临的重大挑战。为了解决金属离子造成的污染，研究人员进行了不断的研究，探索了各种修复方法。冠醚因其离子半径和空腔大小与金属离子匹配良好，具有选择性络合金属离子的能力而备受关注。这种独特的性质使金属离子的定向去除和回收成为可能，并使冠醚在提取和分离过程中越来越受欢迎。综述了冠醚在有价金属离子提取分离中的研究进展，重点介绍了冠醚的提取原理、提取体系以及影响提取过程的关键因素。本研究可为冠醚分离提取有价金属离子的应用提供一定的技术支持。

Review on extraction and separation of valuable metal ions from aqueous solution by crown ether

In recent years, with the rapid development of the economy and society, pollution of valuable metal ions in wastewater has become a major challenge to environmental sustainability. In order to solve the pollution caused by metal ions, researchers have conducted continuous researches and explored various remediation methods. Crown ether has attracted great attention because of its ionic radius and cavity size matching well with metal ions, which makes it have the ability to selectively complex metal ions. This unique property enables the directed removal and recovery of metal ions and makes crown ethers increasingly popular in extraction and separation processes. In this paper, the research progress of crown ethers in the extraction and separation of valuable metal ions was reviewed, with emphasis on the principles, extraction systems and the key factors affecting the extraction process. This study can provide some technical support for the application of separation and extraction of valuable metal ions by crown ether.
