Ion-Imprinted Polymers: Synthesis, Characterization, and Adsorption of Radionuclides

Abstract

Growing concern over the hazardous effect of radionuclides on the environment is driving research on mitigation and deposition strategies for radioactive waste management. Currently, there are many techniques used for radionuclides separation from the environment such as ion exchange, solvent extraction, chemical precipitation and adsorption. Adsorbents are the leading area of research and many useful materials are being discovered in this category of radionuclide ion separation. The adsorption technologies lack the ability of selective removal of metal ions from solution. This drawback is eliminated by the use of ion-imprinted polymers, these materials having targeted binding sites for specific ions in the media. In this review article, we present recently published literature about the use of ion-imprinted polymers for the adsorption of 10 important hazardous radionuclides—U, Th, Cs, Sr, Ce, Tc, La, Cr, Ni, Co—found in the nuclear fuel cycle.

Novel Chemoresistive Sensor for Sensitive Detection of Pb2+ Ions Using an Interdigital Gold Electrode Fabricated with a Reduced Graphene Oxide-Based Ion-Imprinted Polymer

“…The Pb 2+ -IIP unleached was synthesized by bulk polymerization procedure using 4 mM monomer MAA, 20 mM cross-linker EDGMA, 0.3 mM initiator BPO, and (1:9 v/v) DMSO/ACN in the presence of 0.5 mM Pb­(NO 3 ) 2 Briefly, 0.5 mM amount of Pb­(NO 3 ) 2 was dissolved in 10 mL of porogen mixture in the reaction flask to generate Pb 2+ template ions.…”

A monomer and cross-linker were then added to the reaction flask and stirred, sealed for 10 min at room temperature, followed by an appropriate amount of BPO, and stirred until completely dissolved.…”

New Materials and Technologies for Wastewater Treatment

“…The rapid development of the research conducted on these materials resulted in a high chemical variability of each component. Therefore, Kusumkar et al proposed a state of the art of the research on IIPs synthesis and characterization, and their use for the removal of radionuclides [ 8 ]. This review allowed the identification of some sparsely studied radionuclides (i.e., TcO 4 - and Ce 3+ ) that deserved a research effort, and constituted a wealth of information for researchers interested in the IIPs preparation or the selective removal of radionuclides.…”

Uranium Determination in Waters, Wine and Honey by Solid Phase Extraction with New Ion Imprinted Polymer

“…After elution of the ion the cavity formed is complementary with ion geometry, coordination and size, which results in a very high selectivity [ 20 ]. Wide range of ion imprinted polymers (IIP) have been proposed for selective sorption of U mostly in waters [ 21 ]. Different types of IIPs were synthesized and applied in analytical procedures for U determination: IIPs based on binary and ternary complexes of U.…”
