Ion imprinting technology (IIT) aims to recognize ions while retaining the unique virtues of molecular imprinting technology (MIT), namely structure predictability, recognition specificity and application universality. Owing to special coordination or electrostatic interactions, ion imprinted polymers (IIPs) are generally compatible with aqueous media and have advantages over most molecularly imprinted polymers (MIPs). IIPs can achieve effective identification of water-soluble ions, especially heavy metals and radioactive elements that cause increasing concerns. The purpose of this review is to summarize recent advances of ion imprinting, focusing on the current status and challenges in fundamentals and applications that involve almost all types of ions and ion-related molecular imprinting. In addition, various smart strategies are highlighted, such as surface imprinting, stimuli-responsive imprinting, dual/ multiple components imprinting, click chemistry, and microwave-assisted heating. In this review, the elemental periodic table is first utilized as a template to introduce ion classification standards for various IIPs, including main groups, transition elements, actinides, rare earths, metalloids, anion imprinting and secondary imprinting. Finally, the challenges and possible solution strategies plus future trends are also proposed (302 references).

In this work a novel ion imprinted polymer (IIP), based on dipyridyl amine-coated Fe 3 O 4 nanoparticles (NPs), was synthesized as a novel magnetic sorbent for rapid extraction, preconcentration and determination of trace amounts of gold ions. This was characterized by IR spectroscopy, scanning electron microscopy (SEM), elemental analysis (CHN) and thermal analysis (TGA/DSC). The optimum conditions, including pH of sample, eluent type and concentration and also the least amount of eluent necessary for desorption of gold ions and the time of adsorption were obtained. The effect of various cationic interferences on the adsorption of gold, specifically Pt(II) and Pd(II) ions, were evaluated. The analytical efficiency and relative standard deviation values for the determination of gold ions were 98.6% and 1.08, respectively, under the optimum conditions. The limit of detection (LOD) was 0.43 ng mL À1 for gold extraction. The maximum capacity of the IIP modified magnetic nanoparticles was found to be greater than 76 mg g À1 . Furthermore, the accuracy of this method was confirmed using various standard materials. This method was also applied successfully for preconcentration and determination of gold ions in some real samples.

“…Most of the current researches in the solid phase extraction are focused on the use of metal ion-imprinted polymers (MIIPs) owing to their cost effectiveness, high stability in different environments, and high selectivity compared to common separation techniques [22][23][24][25][26][27][28][29]. The ion-imprinted polymer particles are generally prepared by the solution, bulk, suspension polymerization, or surface imprinted technique [30][31][32][33].…”

Metal methacrylate complex was synthesized from methacrylic acid and metal carbonate to prepare metal ion-imprinted polymer (MIIP) particles by the precipitation polymerization method. Three types of metal ions, Cu(II), Ni(II), and Pb(II), were used as the template ions in this synthesis. The produced MIIP particles were spherically welldefined with 0.5-2 µm diameter in the order of Cu(II)-MIIP>Ni(II)-MIIP>Pb(II)-MIIP. The imprinted polymers exhibited a much higher adsorption capacity and selectivity toward the target (template) ion than other competitive metal ions. The MIIP particles, Cu(II)-MIIP, Ni(II)-MIIP, and Pb(II)-MIIP, synthesized in this study guaranteed the selective separation of the target metal ion from the mixtures, although their competitive strengths of the adsorption capacity and selectivity were different.
