Abstract

A Cu(II) ion-imprinted polymer (Cu(II)-IIP) for the selective adsorption and separation of Cu(II) was prepared by modifying the surface of mesoporous silica SBA-15 through surface ion imprinting. The prepared polymer was characterized by Fourier transmission infrared spectra (FT-IR), X-ray diffraction (XRD), Energy disperse spectrometer (EDS), Thermogravimetric analysis(TGA), Scanning electron microscope (SEM), Transmission electron microscope (TEM) and nitrogen adsorption–desorption isotherm. Batch adsorption tests were investigated on the effects of solution pH value, contact time and different initial Cu(II) ion concentrations. The results showed that the Cu(II)-IIP has higher adsorption capacity and selectivity than that of non-imprinted polymer (NIP). The adsorption isotherm followed Langmuir model. The kinetic data well fitted the pseudo-second-order kinetic model compared with the pseudo-first-order kinetic model. The selectivity coefficients for Cu(II)/Cd(II), Cu(II)/Fe(II), Cu(II)/Co(II), Cu(II)/Pb(II) were 3.56, 2.32, 11.75, 4.73, respectively. In addition, Adsorption capacity did not significantly decrease after five adsorption–desorption cycles were completed. demonstrating that the polymer is stable and reusable.
