“…Our previous work 35 was based on the solvothermal method for generating Fe3O4 nanoparticles and the "one-pot" method for synthesizing organic-inorganic hybrid monolithic vinyl functionalized Fe3O4 (Fe3O4@HM) of good chemical and mechanical stability. In the present study, a magnetic Ce(III) ionimprinted polymer (Ce(III)-MIIP) was synthesized, during which Ce(III) was used as the template ions, and AM, ethylene glycol dimethacrylate (EGDMA) and 2,2'-azobisisobutyronitrile (AIBN) were used as the functional monomer, cross-linking agent and initiator, respectively.…”

A novel magnetic Ce(III) ion-imprinted polymer (Ce(III)-MIIP), grafted on organic-inorganic hybrid monolithic vinyl functionalized Fe3O4 (Fe3O4@HM), was synthesized for the first time by using the surface ion imprinting technology, in which Ce(III) was used as the template ion and acrylamide as the functional monomer. After the synthesized nanocomposites were well characterized, some parameters such as pH, adsorption time, eluent type, elution time and eluent volume, which affects the efficiency of magnetic solid phase extraction (MSPE), were studied in the determination of Ce(III). Under the optimized experimental conditions, Ce(III)-MIIP nanoparticles were used as the MSPE matrix, followed by inductively coupled plasma mass spectrometry (ICP-MS) determination with excellent selectivity, strong anti-interference ability, low mass transfer resistance and high adsorption capacity. The limit of detection, enrichment factor and adsorption capacity were 0.008 μg•L −1 , 25 and 67.8 mg•g −1 , respectively. The protocol was validated by analyzing certified reference materials and spike recoveries of complex environmental and mineral samples with satisfactory results. The relative standard deviations for the real samples were 1.7%~7.0%. In view of the advantages of facile preparation, fast adsorption rate, excellent selectivity and high adsorption capacity to Ce(III), the hybrid monolith-assisted Ce(III)-MIIP-based MSPE-ICP-MS protocol is promising for the determination of cerium in real environmental and mineral samples.

“…This approach facilitates the anchoring of functional groups within the pores and prevents pore blocking. 25,[44][45][46][47] To further enhance the selectivity advantages of ion imprinting we employed a double imprinting technique during the synthesis of the magnetic bifunctional ion imprinted sorbent (MBII). In this approach, both the amino and thiol functionalities are imprinted with Cd(II) during the pre-assembly step of the onepot synthesis.…”

Attractive physical, chemical, and biological properties of the noble (precious) metals – ruthenium, rhodium, palladium, osmium, iridium, and platinum (so‐called platinum group metals (PGM)) and gold – result in their wide applications. The main demands for the metals are from autocatalysts; chemical, electrical, and electronic industries; jewelry and investment. Medical applications of some noble metal compounds, in particular those exhibiting anticancer activity, are of great importance. The large variety and complexity of the examined (geological, environmental, industrial, and biological) materials, great chemical similarities and low stability of the noble metal species in solutions, and wide concentration (from sub‐ppb to >99.99%) ranges to be determined make the accurate determination of the metals a difficult analytical problem. Identification and quantification of various chemical forms (elemental, complex) of the metals in the examined samples require methods capable of separation of the analytes from the interfering matrix components and their detection. The choice of a suitable sample preparation procedure and its successful coupling with the detection technique of required selectivity and sensitivity are fundamental factors limiting the quality of the results. Analytical methods applicable in the analysis of the noble metal samples are presented in the article.
