Preparation, adsorption and recognition properties of uranyl ion-imprinted marine facultative fungus mainly modified by phytic acid and tetraethyl silicate

Ion imprinted polymer is a kind of three-dimensional material with special cavity structure. Its cavity site has the function of specifically recognizing and binding target ions. It is a kind of materials that can selectively combine, enrich and remove target ions in the environment. Uranium is an important radioactive element, which has been widely used in nuclear power, military industry, science and technology and other fields. However, the accumulation of uranyl ions in environmental water causes serious health hazards to human body. Therefore, the detection and enrichment of uranyl ions in water is of great significance. In this paper, the theory, technology and application status of ion imprinted polymer for micro detection and adsorption of uranyl particles in wastewater were reviewed, and the development of uranyl ion imprinted polymer was prospected.

Hydroxy Quinoline

Imprinted homopolymer of uranyl ion with aniline (IPAN) and imprinted copolymer with aniline and 8-hydroxyquinoline functionalized aniline (IFPAN) were synthesized. These polymers upon leaching, (IPAN_L and IFPAN_L), give materials suitable for rebinding of uranyl ion selectively from aqueous samples.

Ion Imprinted

Ion imprinted polymer material (IIP) was prepared by forming ternary complexes of uranyl imprint ion with 1-(prop-2-en-1-yl)-4-(pyridin-2-ylmethyl)piperazine and methacrylic acid followed by thermal copolymerization with ethylene glycol dimethacrylate as the cross-linking monomer in the presence of 1,1′-azobis(cyclohexanecarbonitrile) initiator and 2-methoxy ethanol porogenic solvent. HCl solution (5 mol/L) was used to leach out the uranyl template ion from the IIP particles. Similarly, the control polymer (CP) material was also prepared exactly under the same conditions as the IIP but without the uranyl ion template. Various parameters such as solution pH, initial concentration, aqueous phase volume, sorbent dosage, contact time and leaching solution volumes were investigated. SEM, IR and BET-surface area and pore size analysis were used for the characterization of IIP and CP materials. The extraction efficiency of the IIP and CP was compared using a batch and SPE mode of extraction. The optimal pH for quantitative removal is 4.0–8.0, sorbent amount is 20 mg, contact time is 20 min and the retention capacity is 120 mg of uranyl ion per g of IIP. The IIP prepared demonstrated superior selectivity towards coexisting cations and therefore it can be used for selective removal of uranium from complex matrices.
