Salicylic acid complex imprinted polymeric membranes have been prepared by thermal polymerization using polyvinilidene uoride membrane as a support membrane, acrylamide as a functional monomer and ethylene glycol dimethacrylate as a crosslinker. The imprinted membranes are characterized by Fourier Transform Infrared Spectrometer (FT-IR), thermogravimetric analysis (TGA) and scanning electron microscope (SEM). It can be found that the structure of imprinted membranes is different from the supporting membrane, and the surface of the supporting membrane is covered with an imprinted polymer layer after polymerization. Adsorption and permeation binding experiments indicate that imprinted membranes show high speci c binding capacity of template molecule, the selectivity factor of the imprinted membrane for the salicylic acid was 26.4, The optimum polymerization condition is 0.3 mmol salicylic acid, 1.2 mmol acrylamide and 6.0 mmol ethylene glycol dimethacrylate in acetonitrile at 60 C for 24 h.

“…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.…”

Preparation and characterization of Zn(II) ion-imprinted polymer based on salicylic acrylate for recovery of Zn(II) ions

2016

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.

“…In the ionic imprinted technique, adsorption selectivity of metal ion can occur because there are metal ions playing a role as a template and a monomer containing functional groups in polymer synthesis. A releasing of metal ions as template from polymer matrix will cause formation and arrangement of ionic imprinted cavities on ionic imprinted material which will adsorb selectively target ion [10][11][12][13].…”
