Synthesis and evaluation of UiO-66@MIP towards norfloxacin in water

Abstract

Norfloxacin (NOX), a kind of quinolone antibiotic, is widely used in disease treatment and the control of human and livestock products. Due to overuse, norfloxacin has become a common organic pollutant in water. We combine the high specific surface area and high stability of metal–organic frameworks with the high selectivity of molecularly imprinted polymers. By grafting a carbon–carbon double bond on the surface of UiO-66–NH2, a molecularly imprinted layer is formed on the surface of UiO-66–NH2 upon free radical polymerization. The saturated adsorption capacity of UiO-66@MIP reaches 58.01 mg g−1. UiO-66@MIP exhibits high adsorption performance in real water samples and its recoveries range from 96.7% to 98.3%, which demonstrates a higher adsorption capacity and recovery than other molecularly imprinted materials and has potential applications in the removal of norfloxacin in real life.
