“…5 Recently, there are some reports on the application of IIP to preconcentration of the heavy metal ions. 6,7 Chitosan (CTS) is one of the most abundant biopolymers in nature, and has remarkable properties such as nontoxicity, high biocompatibility and biodegradation. 8 The free amido and hydroxyl function abilities of chitosan give it a better ability to chelate ions of transition metals than other natural compounds.…”

The surface-grafting ion-imprinting technology was applied to synthesis of a new Co(II)-imprinted polymer [Co(II)-IP], which could be used for selective removal of Co(II) from aqueous solutions. The prepared polymer was characterized by using the infrared spectra (IR), X-ray diffractometer (XRD), X-ray energy dispersion spectroscopy (EDS) and scanning electron microscopy (SEM). The maximum adsorption capacity values for the Co(II)-imprinted polymer and non-imprinted polymer (NIP) were 22 and 8 mg/g, respectively. The Freundlich equation fitted the adsorption isotherm data well. The applicability of two kinetic models including pseudo-first-order and pseudo-second-order models was estimated on the basis of comparative analysis of the corresponding rate parameters, equilibrium capacity, and correlation coefficients. Results suggested that chemical process could be the rate-limiting step in the adsorption process. And the adsorption of Co(II) on the Co(II)-imprinted polymer was endothermic. The relative selectivity coefficients of the Co(II)-imprinted polymer for Co(II)/Pb(II), Co(II)/Cu(II), Co(II)/Ni(II), Co(II)/Sr(II) and Co(II)/Cs(I) were respectively 11.5, 6.1, 13.8, 9.4, and 8.1 times greater than that of the non-imprinted polymer. Eventually, the desorption conditions of the adsorbed Co(II) from the Co(II)-imprinted polymer were also studied in batch experiments.

“…IIPs have been used for other application than solid phase extraction such as catalytic applications [15] , chromatographic stationary phases [16] , membrane separations [17] and sensors [18][19][20] . IIPs mainly used for the selective SPE of the trace metal pollutants from complex matrices [21][22][23][24][25][26][27][28][29][30][31][32][33] . This selective extraction and clean up cannot possible with the conventional sorbent.…”

SbstractThis work describes the synthesis of new ion-imprinted polymers (IIPs) for selective solid phase extraction of Zn(II) ions from aqueous samples. IIPs were synthesized by copolymerization of salicylic acrylate (SA) as a functional monomer and ethylene glycol dimethacrylate (EGDMA) as a crosslinker in the presence of 2,2'-azobisisobutyronitrile (AIBN) as an initiator. The template ions were removed from IIPs particles by leaching with 0.1 M Ethylenediaminetetraacetic acid (EDTA) which leaves cavities in the particles with the capability of selective extraction of the Zn(II) ions. The monomer and the polymer after synthesis have been characterized by 1 H NMR, 13 C NMR and FT-IR studies. The effect of the pH on the extraction efficiency of Zn(II) ions was studied and optimized in pH around 6. The selectivity of the synthesized IIPs was studied in the presence of Co(II), Cd(II) and Ni(II) ions, and the IIPs showed higher affinity for Zn(II) in the presence of other interfering ions.
