| Abstract: | ABSTRACT The molecular surface imprinted graft copolymer of metal-organic framework MOF-5 with methacrylic acid were prepared by free radical polymerization with dibutyl phthalate as the template molecule using initiator of azobisisobutyronitrile as adsorption system. The prepared MIPs@MOF-5 were characterized by fourier transform infrared spectroscopy, scanning electron microscopy, Brunner?Emmet?Teller measurements, adsorption isotherms, kinetics and selectivity experiments, which showed higher specificity, sensitivity, stability, and better adsorption performance. The results suggested that MIPs@MOF-5 had two sites of adsorption behavior and can recognize sensitively and selectively the template molecules. Moreover, the MIPs@MOF-5 was successfully applied to the analysis of tap water sample. |
