Preparation of Ferrocyanide-Imprinted Pyridine-Carrying Microspheres by Surface Imprinting Polymerization

Diffusive transport of electroactive species in sub-micron diameter pores of membrane electrodes

“…4.2 Å [49], while the FeðCNÞ 3À 6 anion diameter is ca. 6.2 Å [50]. What is more, an anion is solvated, which makes its diameter even bigger.…”

Preconcentration of phosphate ion onto ion-imprinted polymer

“…Ion-imprinted polymers (IIPs) are similar to MIPs, but templated resins have prepared using polyvalent metal ions [26][27][28][29][30]. There are some publications, recently, for the removal of anions by using molecular imprinting technique [31][32][33].…”

Comparison between two commercial uranium resins and a uranyl sulphate imprinted resin based on self-assembling MIT

“…The latter prepared via noncovalent bonds (hydrogen bonding, electrostatic interaction and so on) is widely adopted because the imprinting process is relatively simple, the template can be wipe off easily, and the recognition is even close to natural molecular recognition [6][7][8]. The MIPs prepared via hydrogen bonding are conceptually attractive, but they tend to be limited in utility because of the few choices of monomers, and thus chemistries, that can be used in the imprinting step [9,10]. The polymerization is a critical step in the preparation of these materials due to the constraints of polar solvents such as water.…”

“…As for polymerization methods, numerous MIPs have been prepared by precipitation polymerization followed by crushing and sieving to desired particle size, but this procedure could destroy the imprint sites on the MIPs to a certain extent. Better polymerization procedures have been used for the preparation of MIPs, such as solution polymerization, seed swelling and surface imprinting [9,10]. But suspension and emulsion polymerizations, which are commonly used for preparing ion exchange resins, have been seldom reported.…”

“…Since MIT is an effective technology for selective adsorption, ion exchange resins synthesized by MIT seem to be attractive. Fujiwara and colleagues synthesized imprinted ion exchange resins, using [Fe(CN) 6 ] 2− as template [9]. Cui and colleagues synthesized imprinted polymers with metal ions Cu(II), Ni(II), and Fe(III) as imprinting templates [10].…”
