Summary: The study tested low molecular weight diglycolamide (DGA) extractants for the extraction of europium(III) and americium(III) from nitric acid solutions in n-dodecane and 1-butyl-3-methylimidazolium bis(trifluoromethanesulphonyl) imide (C(4)mim center dot NTf2). Results showed that the resin containing the ionic liquid had higher europium(III) uptake values, while the resin with n-dodecane had a sharp decrease in extraction percentage after three cycles.

Summary: This study tested four extraction chromatography resins and one room temperature ionic liquid for the recovery of plutonium (IV) from nitric acid solutions. The results showed that the efficiency of metal ion uptake was inversely related to the chain length of the attached alkyl groups, and the uptake of Pu(IV) decreased with increasing nitric acid concentration in the lower acidity range, followed by an increase. Additionally, all the tested resins followed the pseudo-second order kinetic model and Langmuir monolayer adsorption model.

Summary: A new aptamer@metal-organic framework (MOF)-functionalized affinity monolithic column was developed for the selective detection of domoic acid (DA) in shellfish. The affinity performance of the system was studied and it exhibited high specificity with little interference of tissue matrixes. The method achieved a significant enhancement in detection sensitivity compared to traditional SPE or MIP adsorbents.

Summary: The study investigated the recovery of ethanol from dilute aqueous solutions using supported ionic liquid membrane (SILM) perstraction. The combination of [THTDP][N(CN)2] as a solvent and polymeric microporous membrane (PVDF-GVHP) showed the best overall performance, with high flux and selectivity maintained for 240 hours. This SILM perstraction system proved to be a promising alternative to energy-intensive purification techniques for extracting ethanol as low as 2 wt% from fermentation broths.

Summary: A method for removing arsenic and recovering antimony from high-arsenic soot was proposed, using a combination of sodium sulfide-sodium hydroxide leaching and aluminum sheet addition. The process effectively achieved high leaching rates for both arsenic and antimony, and achieved a high recovery rate for antimony through the use of lime-precipitation method.

Summary: A method using zinc chloride was developed to purify compounds with pyridine structure from Mitsunobu reaction mixtures, and a sulfide anion was used to release bipyridines from Ullmann coupling reaction mixtures by competitively coordinating the copper ion. These improvements enabled the facile synthesis of the chiral 2,2'-bipyridine ligand (R-a,S,S)-C3-ACBP, achieving an overall yield of 48% at a 7 gram scale within 3-4 days without column chromatography.

Summary: In this study, a CuO-decorated ZnO heterojunction nanocomposite was successfully synthesized using Muntingia calabura leaf extract as a green synthesis agent. The nanocomposite exhibited rice grain-shaped particles with dimensions of 100-250 nm in length and 50-100 nm in width. Antibacterial activity of the nanocomposite was significantly enhanced under illumination due to the generation of free radicals and release of Zn2+ and Cu2+ ions, leading to the destruction of cell membranes. Moreover, the nanocomposite showed light absorption in the visible spectrum and generated H2O2 at a concentration of 25 μM through an oxygen-aerated aqueous media generation experiment. These findings highlight the potential of green synthesized nanomaterials using biological plant extracts for antibacterial applications, as well as the possibility of producing heterostructures using plant extracts.

Summary: The tetrabutylammonium bis (2-ethylhexyl) phosphate [N4444][P204] ionic liquid was synthesized and used to extract copper cyanide complex ions. The extraction process involved the formation of solid samples rich in copper cyanide complex ions at the phase interface through self-assembly of the ionic liquid. The [N4444][P204] IL demonstrated highly efficient extraction of copper cyanide complex ions, with extraction efficiency remaining above 75% even after three cycles.
