“…31−34,38−40 Some polymers were tested for separation of chromium species from real samples, 32,36,39,40 but only two of them were applied in dynamic procedures for their separation from wastewater. 35,37 The aim of our work was to prepare a new selective polymeric sorbent with an imprinted Cr(III)nicotinate complex for the separation of chromium(III) ions. The Cr(III) ion-imprinted polymer was prepared by precipitation polymerisation using acrylamide as the functional monomer, ethylene glycol dimethacrylate as the cross-linking agent, and 2,2'-azobisisobutyronitrile as the radical initiator.…”

A new chromium(III) ion-imprinted polymer (IIP) was prepared from a Cr(III)-nicotinate complex (template), acrylamide (functional monomer), and ethylene glycol dimethacrylate (cross-linking agent) using 2,2'-azobisisobutyronitrile as the radical initiator. IIP was characterised and used as a selective sorbent for the solid-phase extraction of Cr(III) ions. The conditions for dynamic separation of Cr(III) on IIP were optimised. Cr(III) ions are selectively retained on the sorbent in a pH range from 9 to 10 and can be eluted with 4 mol L −1 acetic acid. Cr(III) ions were determined by flame atomic absorption spectrometry (FAAS) with a detection limit of 0.08 µ g mL −1. The method was successfully applied to determine Cr(III) species in wastewater and reference material RES 25.2 with a reproducibility of 1.8%-3.4%.

“…A Cr III -imprinted polymer has been prepared from Cr III -pyrrolidinedithiocarbamate complex, acrylamide functional monomer and ethylene glycol methacrylate cross-linking agent. 136 It was found that Cr III ions could be retained with reasonable efficiency and repeatability (87%, RSD ¼ 3.2%) from a solution of pH 3.50-4.75. Elution of analyte was achieved using 0.2 mol L À1 nitric acid solution.…”

“…Ion-imprinted polymers have various desireable properties such as: the high recognition, chemical and mechanical stability, ease and low cost of preparation as well as high adsorption selectivity towards specific analytes. However, these materials are characterized by low active surface, which confers low adsorption capacities towards specific metal ions [21].…”

A gold(III)-imprinted thiocyanato-functionalized silica network of type SBA-15 was prepared by co-condensation of tetraethoxysilane (TEOS) with thiocyanatopropyltriethoxysilane (TCTES) in the presence of Pluronic123 and Au(III) ions. Compared to the non-imprinted material, the imprint has a higher selectivity and adsorption capacity for Au(III). The maximum static adsorption capacity for Au(III) is 475 mg·g−1 for the ion-imprinted, and 62 mg·g−1 for the non-imprinted sorbent. The imprint was applied to the sorption of Au(III) from digested geological samples prior to its determination by graphite furnace atomic absorption spectrometry. Adsorption is fast and does not substantially prolong the analytical procedure. Under optimum conditions, the detection limit for Au(III) is 2 ng·g−1. The method was validated by analyzing certified reference materials, and results were in good agreement with certified values. The procedure was successfully applied to the separation and determination of gold in complex geological samples. Graphical abstractSchematic presentation of the preparation of ion-imprinted thiocyanato-functionalized mesoporous silica and its application for the preconcentration of gold from digested soils before its determination by slurry sampling graphite furnace atomic absorption spectrometry (GF AAS).
