Abstract
A newly green molecularly imprinted polymer (MIP) for kitasamycin (KITA) was synthesized in water by using 1-allyl-3-vinylimidazolium chloride ionic liquid and 2-acrylamide-2-methylpropanesulfonic acid as co-functional monomer on the surface of poly (styrene-divinylbenzene) particles. The prepared MIP has excellent selectivity for KITA in mixed solution, and approximately 90% of KITA can be bounded onto MIP within the first 30 min. And the MIP exhibited powerful affinity towards KITA with the maximum adsorption amount of 127.06 mg g -1 with the recovery of 92.3–108.8%, and the binding capacity increased within the contact temperature of 25–45 °C. The adsorption mechanism revealed that the synergistic effect of hydrogen bond, π-π interaction and molecule structure was attributed to selectivity of the MIP. Under the optimized condition, a MIP-SPE cartridge coupled with high performance liquid chromatography (HPLC) was developed to determine the residues of KITA in soil, water and muscle samples, and the MIP-SPE cartridge can be regenerated at least 25 cycles. Therefore, the developed MIP-SPE-HPLC strategy can be used as a specific, cost-effective and environmentally-friendly method for identification and determination KITA in environmental samples. A novel eco-friendly molecularly imprinted polymer (MIP) was proposed in water by using 1-allyl-3-vinylimidazolium chloride and 2-acrylamide-2-methylpropanesulfonic acid as bifunctional monomer for the specific adsorption of kitasamycin (KITA). The obtained MIP had excellent selectivity towards KITA and can be used as solid phase extraction for recognizing and separating trace KITA in soil, water and muscle samples. • An eco-friendly hydrophilic kitasamycin MIP was synthesized. • The MIP showed excellent selectivity and adsorption capacity to KITA in water. • The excellent practicability and reusability of MIP-SPE were also demonstrated.
