“…Moreover, the -NH 2 asymmetric vibration caused the absorption peak at 3421 cm −1 [25]. Furthermore, the absorption peaks at 1158 cm −1 and 1260 cm −1 were attributed to the P=O of monomer B-2MP [31]. The existence of the above characteristic peaks proved the successful preparation of Co(II)-MIIP.…”

A novel cobalt ion-imprinted polymer (Co(II)-MIIP) based on magnetic Fe3O4 nanoparticles was prepared by using Co(II) as the template ion, and bis(2-methacryloxyethyl) phosphate and glycylglycine as dual functional monomers. The fabricated material was analyzed by Fourier transform infrared spectroscopy, thermogravimetric analysis, field emission scanning electron microscopy, energy dispersive X-ray spectroscopy, Brunauer–Emmett–Teller, X-ray diffraction, and vibrating sample magnetometer. The adsorption experiments with Co(II)-MIIP, found that the maximum adsorption capacity could reach 33.4 mg·g−1, while that of the non-imprinted polymer (Co(II)-NIP) was found to reach 15.7 mg·g−1. The adsorption equilibriums of Co(II)-MIIP and Co(II)-NIP was established within 20 min and 30 min, respectively. The adsorption process could be suitably described by the Langmuir isotherm model and the pseudo-second-order kinetics model. In binary mixtures of Co(II)/Fe(II), Co(II)/Cu(II), Co(II)/Mg(II), Co(II)/Zn(II), and Co(II)/Ni(II), the relative selectivity coefficients of Co(II)-MIIP toward Co(II)-NIP were 5.25, 4.05, 6.06, 11.81, and 4.48, respectively. The regeneration experiments indicated that through six adsorption–desorption cycles, the adsorption capacity of Co(II)-MIIP remained nearly 90%.

“…Another important application of Fe(III)-IIPs sorbents is focused on the removal of trace Fe(III) from Cr(III)-containing solutions [ 120 , 121 ]. The presence of iron impurities during the fabrication of Cr(III) products has negative effects on the tanning properties of the basic chromium sulfate and on the coloring efficiency of chromium oxide green [ 120 , 121 ]. To solve this problem, Fe(III)-IIP have been prepared either by cross-linking polymerization of AA pre-complexed with Fe(III) using EGDMA as cross-linker, in bulk, followed by the removal of the template with HCl (scheme in Table S5 ) [ 120 ] or by using bis(2-methacryloxyethyl) phosphate (BMAOP) as a ligand for Fe(III) followed by polymerization and leaching of a template (scheme in Table S5 ) [ 121 ].…”

According to the first approach, the functional monomer interacted directly with the template, and therefore, the optimum mole ratio between AA and Fe(III) was determined first and found to be 1:6, the adsorption capacity being maximum at this mole ratio.…”

“…As can be seen in Figure 8 E,F, the highest selectivity factor and the highest relative selectivity factor have been found at a mole ratio of AA to Fe(III) of 9:1, due to the better matching between AA and Fe(III) at this ratio [ 120 ]. The IIP sorbent prepared with BMAOP as a ligand for Fe(III), in a mole ratio of 3:1 ( Table S5 ), displayed a high selectivity in the removal of trace Fe(III) ions from high-concentration basic chromium sulfate solutions, even in the presence of other interfering ions [ 121 ]. Thus, the relative selectivity factors found for the adsorption of Fe(III) in binary systems with Cr(III), Co(II), Ni(II), Cu(II), or Zn(II) were as follows: 2.44, 4.38, 4.17, 1.78, and 4.15 for Fe(III)/Cr(III), Fe(III)/Co(II), Fe(III)/Ni(II), Fe(III)/Cu(II), and Fe(III)/Zn(II) ion pairs [ 121 ].…”

The introduction of selective recognition sites toward certain heavy metal ions (HMIs) is a great challenge, which has a major role when the separation of species with similar physicochemical features is considered. In this context, ion-imprinted polymers (IIPs) developed based on the principle of molecular imprinting methodology, have emerged as an innovative solution. Recent advances in IIPs have shown that they exhibit higher selectivity coefficients than non-imprinted ones, which could support a large range of environmental applications starting from extraction and monitoring of HMIs to their detection and quantification. This review will emphasize the application of IIPs for selective removal of transition metal ions (including HMIs, precious metal ions, radionuclides, and rare earth metal ions) from aqueous solution by critically analyzing the most relevant literature studies from the last decade. In the first part of this review, the chemical components of IIPs, the main ion-imprinting technologies as well as the characterization methods used to evaluate the binding properties are briefly presented. In the second part, synthesis parameters, adsorption performance, and a descriptive analysis of solid phase extraction of heavy metal ions by various IIPs are provided.
