Synthesis of nano-pore samarium (III)-imprinted polymer for preconcentrative separation of samarium ions from other lanthanide ions via solid phase extraction

Synthesis and Characterization of Nanopore MoVI-Imprinted Polymer and Its Application as Solid Phase for Extraction, Separation and Preconcentration of Molybdenum Ions from Water Samples

“…[14][15][16][17] There are some reports on the nanopore IIP preparation and their applications as the solid phase extraction (SPE) sorbent for the preconcentration of the analytes present in trace amounts or their separation from other coexisting species in complex matrix. [18][19][20] Mo VI oxy ion imprinted particle was prepared firstly by the surface metal ion imprinting technique with a sol-gel process on the surface of amino-silica by Ren et al 21 They used Mo VI oxy ion-imprinted as an adsorbent for preconcentration and separation of Mo VI trace amounts from the water samples. In this work nanopore molybdenum(VI)-imprinted and non-imprinted copolymers were synthesized by using methacrylic acid (MAA) as a monomer, ethylene glycoldimethacrylate (EGDMA), as crosslinking agent, and 2,2'-azobisisobutyronitrile (AIBN) as initiator, after removal of Mo VI ions, Mo VI -imprinted polymer was used for solid phase extraction and preconcentration of Mo VI from aqueous solutions.…”

Magnetic nanoparticles with an imprinted polymer coating for the selective extraction of uranyl ions

“…Such cavities are complementary in shape, size and chemical functionality of the imprinted ion that makes it possible to selective rebind to this ion in the presence of other ions [13]. The selectivity of these materials is predominant advantage in separating and analyzing of the imprinted ion from complicated samples and depends on the coordination geometry, coordination number, the charge and size of the imprinted ion [14,15]. Besides, imprinted polymers are characterized by high chemical and thermal stability as well as good mechanical properties.…”

Design and synthesis of chelating diamide sorbents for the separation of lanthanides

“…Many efforts have been made in an attempt to achieve these lanthanide separations. Various techniques, such as capillary eletrophoresis [17,18], coprecipitation [19], solid phase extraction [20][21][22][23][24][25], liquid-liquid extraction [26][27][28], and including cloud point extraction [29], have been developed for separating lanthanides in a variety of matrices. Among these methods, liquid-liquid extraction in conjunction with various organic extractants has proved to be promising, and is currently used for commercial separation and purifying of lanthanides in large scale production [30].…”
