Abstract

In this project microextraction systems using electric field, so-called electromembrane extraction (EME), will be developed. The main aim of this project is the use of EME to enhance the speed, the extraction efficiency and the detectability of analytes in capillary electrophoresis methods. A new configuration of EME using separated electrolysis is proposed, as well as strategies to obtain efficient microextractions of polar compounds. The developed EME systems will be evaluated, optimized, and applied for extraction and preconcentration of phenolic acids in olive oil and sulfonamide residues in bovine milk and chicken egg. (AU)
