Stoichiometrically Imprinted Polymer SPE of Fluoroquinolones

Researchers from Universidad Complutense de Madrid (Madrid, Spain) and Universität Dortmund (Dortmund, Germany) used a molecularly imprinted polymer (MIP) solid-phase extraction method in the analysis of fluoroquinolone antibiotics in environmental water samples. The MIP was prepared using enrofloxacin as the template and a stoichiometric quantity of urea-based functional monomer to target the oxyanionic moeities in the template molecule. They characterized the polymer using nitrogen adsorption–desorption isotherms and scanning electron microscopy.
