“…857 The utility of initiation by -irradiation 402,403,410,530,574,[858][859][860][861] was also demonstrated by Biju et al in the preparation of imprinted adsorbents for dysprosium ion 545 which proved superior to those prepared by thermal means. 544 The use of iniferters such as benzyl-N,N-diethyldithiocarbamate, which are photochemical quasi-living free radical polymerization initiators, has allowed the facile preparation of graft MIP layers on membranes, beads and surfaces. 766,862 The effect of temperature and other polymerization conditions.…”

“…This 'fixed ligand and coordination shell' transition metal approach was recently extended by Disalvo et al 544 to carry out alkene epoxidation using an imprinted modified Jacobsen's catalyst. The conventional Jacobsen catalyst is highly effective in the enantioselective epoxidation of non-functional cis-alkenes but immobilization of the catalyst, while desirable for its separation from reagents and products, results in loss of activity and selectivity.…”

Over 1450 references to original papers, reviews and monographs have herein been collected to document the development of molecular imprinting science and technology from the serendipitous discovery of Polyakov in 1931 to recent attempts to implement and understand the principles underlying the technique and its use in a range of application areas. In the presentation of the assembled references, a section presenting reviews and monographs covering the area is followed by papers dealing with fundamental aspects of molecular imprinting and the development of novel polymer formats. Thereafter, literature describing attempts to apply these polymeric materials to a range of application areas is presented.

“…6,7 These polymers have a high affinity and selectivity for the target ion, are easy to produce, are low cost and stable. Separation/ preconcentration using IIPs has been employed, for example, in the separation of Fe 3+ from plant and water samples with a posterior determination by ICP OES, 7 of Dy 3+ from synthesized seawater and spectrophotometric determination 8 , and of Cu 2+ , Ni 2+ , Pb 2+ and Zn 2+ from celery samples with determination by ICP-MS. 9 In spite of the outstanding performance by IIPs for metal ion adsorption, a survey of the literature shows that few studies have been devoted to zinc preconcentration and further determination by FAAS. A Zn(II) IIP was recently prepared with acryloyloxyquinoline (8-AOQ) as the monomer.…”

In this paper, we describe the synthesis of an ion imprinted polymer (IIP) by homogeneous polymerization and its use in solid-phase to extract and preconcentrate zinc ions. Under optimal conditions (pH 5.0, preconcentration flow rate of 12.0 mL min -1 , and eluted with 1.0 mol L −1 HNO 3 ) this procedure allows the determination of zinc with an enrichment factor of 10.2, and with limits of detection and quantification of 1.5 and 5.0 μg L −1 , respectively. The accuracy of our results was confirmed by analysis of tap water and certified reference materials: NIST 1570a (Spinach leaves) and NIST 1515 (Apple leaves).

“…Since the affinity of ligand affects directly on selectivity for an ion template, the right selection of the functional monomer is important. [12] There are some commercial monomers such as 4-vinyl pyridine (VP), styrene, and methacrylic acid that have been used extensively in ion-imprinted polymers. These monomers are used by themselves or with another compound for complexing the ion template before or during the polymerization.…”

Among the toxic metals, mercury (Hg) is a highly toxic element, and hence, a suitable technology is required to remove it. An imprinted polymer exhibiting a high sensitivity for mercury (II) in aqueous solution is presented. Polymer particles imprinted with mercury (II) were synthesized by polymerizing aminothiophenol. The imprinted polymer was characterized by Fourier transform infrared spectroscopy, UV-vis spectroscopy, X-ray diffraction analysis, and scanning electron microscopy. Relative selective coefficients (k′) of the imprinted polymer evaluated from selective binding studies between Hg 2+ and Cu 2+ or Hg 2+ and Cd 2+ were 64 and 27, respectively. These values indicated highly favored Hg 2+ extractions over the two competing ions. The polymer has high analytical potential for selective extraction and pre-concentration of mercury (II) ions in the presence of closely related ions. Here we report simple synthesis of polymer with high selectivity and fast adsorption capability of Hg (II) ion over similar charge cations such as Cd (II) and Cu (II). The study shows that the polymer has a potential intern of reusability and high stability.
