Fabricated Alginated Beads With a Polymeric Natural Deep Eutectic Solvent for Green Micro-Solid Phase Extraction of Pesticide in Tea Leave Sample

Abstract

The background of the study delves into the investigation of alginate beads manufactured with a polymeric natural deep eutectic solvent (NADES) for eco-friendly micro-solid phase extraction (µ-SPE) of pesticides from tea leaves. This environmentally conscious approach targets the extraction of specific pesticides like diazinon, chlorpyrifos, p,p-DDE, and dieldrin. The study underscores the green and sustainable nature of pesticide extraction, emphasizing the enhanced selectivity and efficiency achieved with alg-NADES beads. The synthesis of these beads employs an encapsulation method, and their characteristics are analyzed using ATR-FTIR and FESEM analyses.
