Promising menthol-based (Deep) eutectic solvents for removal of inorganic species

Abstract

Despite the development of instrumental methods in analytical chemistry, the problem of matrix effects still remains. In the case of the analysis of elemental impurities [1], which is necessary for quality control of pharmaceuticals, food products, miscellaneous materials, and environmental control, to overcome this problem, it is often essential to separate and preconcentrate analytes at the sample preparation stage.
