Dispersive liquid–liquid microextraction based on hydrophobic deep eutectic solvents: Application for tetracyclines monitoring in milk
TL;DR: In this article, eleven hydrophobic deep eutectic solvents (hDESs) based on some naturally occurring fatty acids, alcohols, and choline chloride were synthesized and evaluated as green extractants in the dispersive liquid-liquid microextraction (DLLME) of oxytetracycline, tetracyCLine, and doxycycline.
