Abstract

Recovering, removing, or concentrating metal ions from wastewater containing metal ions is critical because a negative impact can be generated on living organisms by metal-contained wastewater, which contains high concentration of metals, when it is discarded into the environment without pretreatment. In this work we used deep eutectic solvents (DESs) dissolved in heptane as extractants to separate the metal ions from aqueous media with solvent extraction technique and found that DES composed of lidocaine and decanoic acid was a great extractant with extractability that reached 100% for interested metal ions. All the metal ions in the experiment were completely stripped out using 1.0 M of hydrochloric acid. DES can be employed as an extractant of metal ions for three extraction cycles with extractability exceeding 90%.

用深共晶溶剂萃取Co(II)、Ni(II)、Cu(II)和Mn(II)

从含金属离子的废水中回收、去除或浓缩金属离子是至关重要的，因为含有高浓度金属的含金属废水在没有预处理的情况下被丢弃到环境中，会对生物产生负面影响。本研究以溶解于庚烷中的深度共晶溶剂(DESs)为萃取剂，采用溶剂萃取技术分离水介质中的金属离子，发现由利多卡因和癸酸组成的DES是一种很好的萃取剂，对感兴趣的金属离子的提取率可达100%。用1.0 M盐酸完全剥离实验中的所有金属离子。DES可作为金属离子的萃取剂，萃取三次，萃取率超过90%。

期刊介绍： Solvent Extraction Research and Development, Japan (Solvent Extr. Res. Dev., Jpn.) is a periodical issued from Japan Association of Solvent Extraction (JASE) containing papers dealing with all aspects of solvent extraction and their related methods, underlying principles, and materials. Original articles, notes, technical reports, and critical reviews will be considered for publication. Original articles must be of reasonably broad scope and significance to the solvent extraction. Notes will originally describe novel work of a limited nature or especially significant work in progress. Authors can contribute some information of novel techniques, equipment or apparatus, reagents and diluents for solvent extraction as technical reports. Critical reviews will be received from the authors to whom the editorial committee asked to contribute.
