Synthesis of Zn(II) ion-imprinted solid-phase extraction material and its analytical application

Synthesis, characterization and application of ion imprinted poly(vinylimidazole) for zinc ion extraction/preconcentration with faas determination

“…A Zn(II) IIP was recently prepared with acryloyloxyquinoline (8-AOQ) as the monomer. 10 Shakerian et al 11 synthesized a new Zn(II) IIP using styrene as the monomer, ethylene glycol dimethacrylate (EGDMA) as the cross-linking agent and 8-hydroxyquinoline as the chelating agent for zinc. In these studies, auxiliary chelating agents must be used to form the binding sites for polymers and the synthesis procedures are very tedious.…”

Correlation of Ionic Imprinting Cavity Sites on the Amino-Silica Hybrid Adsorbent with Adsorption Rate and Capacity of Cd2+ Ion in Solution

“…In the ionic imprinting technique, adsorption selectivity of metal ions can be produced because existence of metal ions plays a role as a template and a monomer containing functional groups in a polymer synthesis. Releasing of metal ions as template from a polymer matrix will cause a formation of ionic imprinted cavities and an arrangement on the ionic imprinted material which will bind target ion selectively [19][20][21] . In addition, the ionic imprinted material is relatively cheap and it can be stored at room temperature for a long time.…”

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

“…Previously, for ion imprinting of zinc ions, following monomers have been used: styrene [26] , methacrylic acid [23] , 8-acryloyloxyquinoline [28] , 4-vinylpyridine [24] , 2-(diethylamino) ethyl methacrylate [22] , 4-vinylpyridine [29] . While the following chelating agents have been used for the selective interaction with zinc ions: oxine [26] , 3,5,7,20,40-pentahydroxyflavone [23] , 2,2'-bipyridyl [24] , 8-hydroxyquinoline [22] , 2,2'-bipyridyl [29] .…”

“…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.…”
