Extraction of Cefquinome from Food by Magnetic Molecularly Imprinted Polymer
Author(s): Aggarwal S, Rajput YS, Sharma R and Pandey AKAggarwal S, Rajput YS, Sharma R and Pandey AK
Objectives: Cefquinome is a fourth generation cephalosporin with broad spectrum antimicrobial activity. It is commonly used against respiratory tract diseases, acute mastitis, calf septicemia and foot rot in livestock. Clean-up step in sample preparation is invariably required for avoiding interferences in assay from other components. It is envisaged to prepare molecular imprinted based polymer with desired selectivity for cefquinome. Method: Imprinted polymer was synthesized over the surface of magnetite using methacrylate (monomer) acid and ethyleneglycoldimethacrylate (crosslinker) in the presence of cefquinome (imprint molecule). Magnetite was prepared by co-precipitation of 1.98 g FeCl2.4H2O and 5.41 g FeCl3.6H2O. Magnetic non-imprinted polymer was prepared similarly in absence of cefquinome. Selectivity in different solvent was calculated from partition coefficient values in imp.. View More»
