Recent advances in dispersion strategies for dispersive liquid-liquid microextraction from green chemistry perspectives

Asmaa Kamal El-Deen et al.

Summary: Dispersive liquid-liquid microextraction (DLLME) has been a widely used sample preparation technique since its introduction in 2006. Efforts have been made to improve its efficiency, accessibility, miniaturization, and environmental friendliness. The dispersion of extraction solvent in aqueous samples, typically achieved using hazardous dispersive solvents, is a crucial step in DLLME. Greener dispersion techniques have been developed to address the environmental risks posed by these solvents. This review summarizes the current trends in dispersion strategies for DLLME, including the use of green dispersers and physical/chemical dispersion approaches, and highlights the most significant strategies applied and published to date. The challenges and future perspectives of these approaches are also discussed, offering new research directions and supporting existing theories.
