Binding behavior of Fe³⁺ ions on ion‐imprinted polymeric beads for analytical applications

Abstract

ABSTRACT:We used a molecular imprinting approach to achieve specific metal binding utilizing N-methacryloyl-(l)-cysteine methyl ester (MAC) as a metal-complexing ligand. MAC was synthesized using methacryloyl chloride and cysteine methyl ester.

Synthesis, characterization and application of a novel ion-imprinted polymer for selective solid phase extraction of copper(II) ions from high salt matrices prior to its determination by FAAS

“…Different approaches have been proposed for synthesis of IIPs, including crosslinking bifunctional reagents with linear chain polymers, chemical immobilization of vinylated ligands in the polymer matrix, surface imprinting by emulsion polymerization and trapping of a non-vinylated chelating agent inside the polymer matrix [21]. A number of different IIPs and their applications have been reported for selective separation and preconcentration of Pd(II) [15,16], Dy(III) [22,23], Er(III) [24], UO 2 2+ [25][26][27], Cu(II) [28][29][30][31][32][33][34][35][36], Cd(II) [37], Ni(II) [38,39], Al(III) [40], Zn(II) [41], Pb(II) [42], Fe(III) [43], Cr(III) [44], Hg(II) [45], Ag(I) [46] and Sc(III) [47].…”

Synthesis and characterization of nano-pore thallium (III) ion-imprinted polymer as a new sorbent for separation and preconcentration of thallium

“…The high selectivity of IIPs can be explained by the polymer memory effects towards the metal ion interaction with a specific ligand, coordination geometry, metal ion coordination number, charge and size [9]. Numerous studies on ion-imprinted polymers and their use for selective separation and preconcentration of metal ions have been reported: UO 2 (II) [10][11][12], Cd(II) [13], Pd(II) [14][15][16][17], Cu(II) [18][19][20][21], Fe(III) [22,23], Hg(II) [24,25], Ni(II) [26,27], Cr(III) [28] and Zn(II) [29].…”

Synthesis and application of ion-imprinted polymer for extraction and pre-concentration of iron ions in environmental water and food samples

“…Then, 10 mL of concentrated nitric acid was added to sample and the mixture was heated at 220 o C for 1 h. After cooling to room temperature, 5 mL hydrogen peroxide was added to the mixture and heated for 1 h and resulting mixture was diluted by deionized water [21,22], adjustment of the pH was performed by using of sodium hydroxide and hydrochloric acid.

“…Ion imprinted polymers (IIPs) are similar to molecular imprinted polymers (MIPs), But in IIPs after the imprinting process, the metal ions are detected [9][10][11][12]. Easy preparation and high selectivity of IIPs have developed using of the ion imprinted technology.…”
