Ionic Liquid-Based Microextraction and Determination of Components in Food-Related Products
Ionic liquids (ILs) are non-molecular solvents, which result from combinations of organic cations and various anions. ILs have many unique properties, including variable viscosity, high conductivity, high thermal stability, almost negligible vapor pressure, and a multitude of varying solvation interactions [1, 2]. The use of ILs has been a hot research topic in analytical chemistry in recent years due to their outstanding properties.
Public concerns over food safety urge sensitive, rapid, and accurate detection of components and agricultural contaminants in food. Food is a complex mixture of a wide variety of chemicals. It is an analytical challenge to extract analytes of interest from food samples considering the multiplicity of food matrices and their complexity . Using green approaches, there has been an increasing number of works employing ILs to extract food samples in recent years. Preconcentration method was usually used combined with these techniques to...
