Recent advances in ionic liquid-based microextraction for pesticide residue analysis in food and environmental samples

detection limits, and more than 90% solvent reduction compared to traditional methods. IL-based microextraction methods significantly reduce solvent consumption while maintaining high analytical performance. Remaining challenges, such as IL viscosity, synthesis cost, and limited biodegradability, are discussed with advances in biodegradable, task-specific, and hybrid IL-deep eutectic solvent systems. Overall, IL-assisted microextraction offers a sensitive, sustainable, and scalable approach for next-generation pesticide residue analysis.
