A novel water-compatible molecularly imprinted resin was prepared in a green solvent deep eutectic solvent (DES). Resorcinol and melamine, as functional monomers with an abundant hydrophilic group, such as –OH, –NH2 and –NH–, were introduced into the molecularly imprinted resin (MIR). Three DESs (choline chloride-ethylene glycol, tetramethylammonium bromide-ethylene glycol and tetramethylammonium chloride-ethylene glycol) were used to synthesize the molecularly imprinted resin. The resulting deep eutectic solvent-based molecularly imprinted resins (DES-MIRs) were then applied to the adsorption of quinolones in water. The adsorption process of DES-MIRs followed the static adsorption model, Langmuir isotherm (R2≥0.9618) and kinetic model pseudo-second-order (R2>0.9814). The highest theory adsorption ability of the three kinds of DES-MIRs was more than 23.79 mg/g. The LODs of DES-MIRs in SPE was less than 0.018 mg/L. The recoveries of this method at three spiked levels were 88.7–94.5%, with RSD of ≤4.8%. |
