Abstract

A green, simple, sensitive, rapid and low cost in-situ solvent formation microextraction technique derived from liquid−liquid microextraction method based on the use of green solvent such as functionalized ionic liquids was described. In this method, two metal ions in the aqueous phase were simultaneously extracted to the organic phase (or functionalized ionic liquid). Here, at the beginning of the microextraction process, the functionalized ionic liquid (FIL) firstly was miscible in the aqueous phase for complex formation with ions with the highest possible yield, and after changing its properties, FIL was converted to the immiscible FIL and separated from the aqueous phase. To obtain optimum extraction conditions, main analytical parameters including the limit of detection, relative standard deviation, linear dynamic range and enhancement factor were investigated. Finally, the ability of the method to analyze some real water and saline samples was tested, and good results were obtained.

基于功能化离子液体的原位溶剂形成微萃取法同时浓缩测定镉和铅离子

摘要

描述了一种绿色、简单、灵敏、快速和低成本的原位溶剂形成微萃取技术，该技术源自基于使用绿色溶剂（如官能化离子液体）的液-液微萃取方法。在该方法中，水相中的两种金属离子同时被萃取到有机相（或功能化离子液体）中。在这里，在微萃取过程开始时，功能化离子液体（FIL)首先与水相混溶，以尽可能高的产率与离子形成络合物，并在改变其性质后，将 FIL 转化为不混溶的 FIL 并与水相分离。为获得最佳提取条件，对检测限、相对标准偏差、线性动态范围和增强因子等主要分析参数进行了研究。最后，对该方法对部分真实水和盐水样品的分析能力进行了测试，取得了良好的效果。
