Nine metal complexes formed by three symmetric β-diketonates (viz., acetylacetonate (acac), 1,1,1,3,3,3-hexafluoro-acetylacetonate (hfac), and 2,2,6,6-tetramethylheptane-3,5-dionate (tmhd)) ions (with different coordination geometries, viz., BeII - tetrahedral, CuII square planar, PbII "swing" pyramidal) were investigated. The study combines structural analyses, vibrational spectroscopic techniques, quantum chemical calculations with the aim of bridging crystal structure, electronic molecular topology, far-infrared (FIR) characteristics. effect intramolecular interactions on structural, electronic, features is center this study. structure Be(tmhd)2 also reported discussed for first time. A complete review experimental IR spectra offered; discrepancies in assignments some peaks are revealed among published works. Anharmonic effects considered acac complexes; however, they negligible FIR modes. systematic comparison between computed experimentally measured data allowed us to design an inexpensive, yet efficient computational protocol investigate large polynuclear complexes.

Surface engineering of chak’o nano-clay with iron oxide and APTES for enhanced heavy metal adsorption in water treatment

F1000Research, Год журнала: 2025, Номер 14, С. 334 - 334

Опубликована: Март 27, 2025

Background The heavy metal contamination of water leads to major environmental and health problems throughout the Mantaro River basin area. study assesses adsorption capacity surface-modified chak’o nano-clay for extracting lead (Pb2+) arsenic (As5+). Methods Surface modifications unmodified were achieved using through Aminopropyltriethoxysilane (APTES), iron oxide (Fe3O4), combined APTES + Fe3O4 particles. Adsorption performance was assessed batch experiments over 8 hours. BET XPS analyses conducted determine surface area, pore volume, functional group availability. kinetics modeled a pseudo-second-order model, equilibrium data analyzed Langmuir isotherm. Results dual modification produced maximum removal capacities which led 95–100% Pb2+ As5+ analysis demonstrated that area (300 m2/g 375 m2/g) volume (0.420 cm3/g 0.600 cm3/g) as well availability increased substantially thus resulting in improved adsorption. model fit kinetic while isotherm behavior describe monolayer treatment combination with generated an adsorbent better magnetic properties electrical conductivity improving its recovery potential structural stability. dual-modified showed high stability during three cycles desorption tests because it maintained more than 90% original process. Conclusion research shows specialized treatments deliver advanced absorption abilities positions leading choice sustainable system remediation.
