Recently, Zhang Feng, chief expert team of the Chinese Academy of Inspection and Quarantine Sciences, has made progress on magnetic nano-pretreatment materials and prepared a new magnetic porous organic polymer ([email protected]@UPOPs) modified with urea functional groups under mild conditions and successfully applied For the enrichment, purification and detection of 5 quinolone veterinary drug residues in milk, eggs, and chicken, the amount of material is only 2 mg, and the extraction time is only 2 minutes. It can still maintain a good purification effect after 8 times of repeated use.
