Summary: In this study, a highly selective ion-imprinted brewer's spent grain (IIP-BSG) adsorbent was prepared using a high monomer/template molar ratio for efficient removal of uranyl ions from wastewater. The IIP-BSG exhibited high adsorption capacity, selectivity, and reusability, and showed potential for selective separation and concentration of U(VI) from nuclear wastewater and mine water.

Summary: This research presents the first reported example of a chiral molecular uranyl complex in solution exhibiting circularly polarized luminescence. The uranyl chiroptical activity is enabled by complexation with the chiral carboxylate ligand ibuprofen. The binding of sodium ibuprofenate salts with [UO2Cl2(thf)(2)](2) creates tris complexes that display luminescent properties under visible and UV excitation.

Summary: In this study, a selective magnetic molecularly imprinted polymer (MMIP) was successfully synthesized and applied as sorbent in magnetic molecularly imprinted solid-phase extraction (MMISPE) for the selective extraction of a mixture of five herbicides. The optimized MMISPE method combined with HPLC-DAD showed low detection and quantification limits, as well as good accuracy and precision. The MMIP sorbent demonstrated remarkable reusability without loss in extraction capacity.

Summary: Cellulose was used as raw material for the production of sorbent microspheres for selective separation of uranyl ions. An amidoxime cellulosic derivative (AOCE) was synthesized by Michael addition followed by amidoximation reaction, and microspheres of ion-imprinted U-AOCE sorbent were made by crosslinking the UO22+ polymer complex with glyoxal and eluting the coordinated ions with H+/EDTA. The adsorption capacity of U-AOCE was significantly higher with enhanced adsorption selectivity for UO22+. The primary adsorption process involved coordination between UO22+ and the-NH2 and-OH groups of the amidoxime units.

Summary: Amino-phenolic chitosan derivative was used to imprint uranyl ions, resulting in a high-efficiency sorbent material (U-APCS) with improved selectivity and adsorption capacity for UO22+. The adsorption mechanism was determined to be chemisorption or coordination, and the adsorption followed a pseudo-second-order kinetic model and a Langmuir isotherm model. Thermodynamic analysis indicated that the adsorption of UO22+ was endothermic and spontaneous.

Summary: This paper presents a comprehensive study on the fabrication of specific magnetic molecularly imprinted polymer (MMIP) for the analysis of aceclofenac from spiked plasma samples. The optimization step involved synthesizing bulk polymers from ethylene glycol dimethacrylate and various functional monomers, and assessing their binding capacities in the presence of different templates. The results showed that polymers molecularly imprinted by allylamine or 4-vinyl-pyridine had the highest binding capacities and specificity. The MMIP containing optimized molecularly imprinted external layer was then used for magnetic solid phase extraction. The total recoveries of aceclofenac demonstrated the capability of the MMIP as a selective clean-up sorbent for complex samples like human plasma.
