“…IIPs retain all the virtues of MIPs, but they can specially recognize the template ion. In recent years, IIPs as selective sorbents for template ions have received much attention, and their applications in selective preconcentration, separation, and enrichment of ions as well as in the removal of toxicant ions from aqueous medium for protecting the environment have been reported. − But then, most of the reported IIPs are metal ion-imprinted polymers, whereas anion-imprinted polymers are seldom recorded in the literature. , In the metal ion-imprinting process, the selectivity of a polymeric adsorbent is based on the coordination geometry and coordination number of the ions as well as on ionic charges and sizes. , The aim of this work is to prepare the arsenate anion surface-imprinted material and to evaluate its ion recognition ability so as to supply a new solid adsorbent for highly effective removal of the arsenic pollution in water. Ion exchange will play a key role in the present designed anion-imprinting process.…”

By molecular design, a new ion surface-imprinting technique was set up based on surface-initiated graft-polymerization, and arsenate anion surface-imprinted material with high performance was prepared for the first time. A redox initiating system was constituted by the amino groups on the surface-modified silica gel particles and the ammonium persulphate in the solution. The cationic monomer 2-methacryloyloxyethyl-trimethyl ammonium chloride (DMC) was used as functional monomer and N,N′-methylenebisacrylamide (MBA) was used as cross-linker. In the solution, the monomer molecules were arranged around the template ion, arsenate anion, via ion exchange action, and then the arsenate anion surface-imprinting was carried out along with the surface-initiated graft-polymerization of DMC and MBA, forming arsenate anion surface-imprinted material IIP-PDMC/SiO2. The experimental results show IIP-PDMC/SiO2 possesses specific recognition selectivity and excellent binding affinity for arsenate anion. The selectivity coefficients of IIP-PDMC/SiO2 for arsenate anion are 8.814 and 7.898 relative to chromate and nitrate ions, respectively.

“…5 IIPs can also be integrated into sensors 6 and employed as stationary phases in chromatographic columns. 7 Previous investigations have shown that ion-imprinted ethylene glycol dimethacrylate and methacrylic acid (MAA) copolymers have large distribution coefficients but are not always characterized by a significant imprinting effect. 8 This issue may be attributed to the competitive interaction between metal ion and crosslinker moieties in the polymer matrix.…”

Ion-imprinted divinylbenzene and methacrylic acid copolymers for rare-earth element adsorption with crosslink ratios 60 and 40% have been synthesized. Ion imprinting has been carried out via the trapping approach. Alizarin red S has been incorporated in the polymers as a nonvinylated ligand. The obtained materials were characterized via scanning electron microscopy and Fourier transform infrared spectroscopy. Synthesized polymers exist as gel-type nonporous spherical agglomerates from 2 to 6 μm with low surface areas. The sorption properties of the synthesized polymers with respect to lanthanides in static and dynamic modes have been studied. The most efficiently synthesized materials extract rare earth elements from solutions at pH 4−7. The maximum sorption capacity of the obtained polymers with regard to Gd is around 0.5 mmol/g. According to the obtained results, the imprinted polymer with a crosslink ratio 60% is characterized by the highest values of distribution coefficients for lanthanides. The total lanthanide breakthrough capacity for this polymer is 0.861 μmol/g. The adsorption column has been constructed using the imprinted polymer with a crosslink ratio 60%. The column extraction and preconcentration procedure for the trace Eu content determination in the strontium iodide recycled material by inductively coupled plasma−atomic emission spectrometry at a level of 1 × 10 −6 % (mass) has been proposed.

In this study; a novel all‐solid‐state type potentiometric microsensor based on ion‐imprinted polymer (IIP) has been developed for Cu(II) sensing. The IIP was synthesized by suspension polymerization by using Cu(II) ion, methacrylamide, methacrylic acid and ethylene glycol dimethacrylate as template, functional monomers and cross‐linker respectively. The resultant Cu(II)‐imprinted polymer was used as ionophore in the structure of the PVC membrane to obtain a selective potentiometric response towards Cu(II) ions. The fabricated microsensor exhibited a highly selective Nernstian response (28.6±2.2 mV per decade) over the concentration range of 10−1 to 10−6 mol L−1 of Cu2+ ion for 2 months without any considerable divergence in potentials. The response time of the microsensor was considerably short (less than 15 s) and its detection limit was determined as 7.6×10−7 mol L−1. The microsensor was effectively performed in the pH range of 4–7. The microsensor was successfully used as an indicator electrode in the potentiometric titration of Cu(II) ions with EDTA. The proposed microsensor was also used for the determination of Cu(II) contents of some environmental water samples. The obtained potentiometric results were in good harmony with the results obtained by the AAS method.
