Abstract: By combining quantum dots technique with ion tracing technique, ion imprinted polymers were prepared by bulk polymerization methed using cadmium(II) as template element, CdSe/CdS quantum dot as fluorescent component, methacrylic acid as functional monomer, ethylene glycol dimethacrylate as crosslinking agent and azobisisobutyronitrile as initiator. The polymers were characterized by such instruments as X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (IR) and comprehensive thermal analysis (TG). The adsorption and fluorescence properties of the polymers were investigated by adsorption and fluorescence quenching experiments. The results showed that there are a large number of imprinted holes in the imprinted polymer, which also demonstrated desirable adsorption and fluorescence properties. This polymers were expected to be used as a solid phase extractant in the field of separation and enrichment.
Template and target information: cadmium ion, Cd(II)
