This work reports the preparation of molecularly imprinted polymers (MIPs) selective to cephalosporin (CF) antibiotics, and their application as molecularly imprinted solid-phase extraction (MISPE) sorbents for the determination of these antimicrobials in milk samples. Several functional monomers and cross-linkers have been screened to select the best combination that provides high selectivity for the simultaneous multiresidue extraction of cefthiofur (THIO), cefazolin (AZO), cefquinome (QUI… CONTINUE READING
