New adsorbents of DSAC@ZIF-8 (0.05:0.6) and were prepared using date seed activated carbon (DSAC) loaded at zeolitic imidazolate framework-8 (ZIF-8).The obtained (0.1:0.6) characterized by Fourier-transform infrared spectroscopy, scanning electron microscopy, powder X-ray diffraction, nitrogen adsorption/desorption tests 77 K revealed the surface area to be 460.23 m 2 /g for (0.1:0.6).This material showed a high affinity Gentian violet (GV) uptake from aqueous solutions: maximum sorption...
Pollution that arises from textile industries is a serious environmental issue, and successful purifying has thus far proven to be difficult. In this study, environmentally safe Zr-metal-organic frameworks (Zr-MOF) were used develop strategy for removing Methylene Blue (MB) water contaminants. The elimination of MB in wastewater samples by Zr-MOF showed good adsorption capability. SEM, FT-IR, XRD, XPS, surface area confirmed large 1498 m2/g besides microporous material having pore diameter...
Activated carbon from apricot seeds (ASAC) was successfully made using a low-cost, straightforward synthesis process. With the use of various instruments, including XRD, XPS, FT-IR, SEM, and TEM, adsorbent demonstrated. The surface area ASAC that given also shown to be 436.8 m
ABSTRACTDue to inadequate pharmaceutical wastewater treatment, anticancer contaminants from the industry frequently end up in aquatic environment where they endanger life and humans. As a result, appropriate treatment of that contains agents is crucial for pollution prevention. The purpose this work assess effectiveness Fe3O4@ZIF-8 nanocomposite as an adsorbent remove chemotherapeutic drugs doxorubicin (DOX) aqueous solution. SEM, XRD, BET, FT-IR, Zeta potential, point zero charge analysis...
Green synthesis of Fe (III), Cu (II), Zn (II) and Ni (II)‐Schiff's‐base complexes from 2‐oxo‐ N ‐(pyridine‐2‐yl)‐2‐(2‐(1‐(pyridin‐2‐yl)ethylidene)hydrazinyl)acetamide(H 2 L)ligand. All new were characterized via several spectroscopic analytical techniques, to establish their molecular structural formulae. appeared have 1:1 molar ratio (M:L). The ligand contributed as a neutral poly‐dentate towards the metal ions. Moreover, material‐studio program was used predict most fitted atomic‐skeletons...
We have successfully synthesized new oxovanadium (IV) complexes with dimedone derivatives and their structure were confirmed by elemental analyses, spectroscopic techniques (FT‐IR, UV–visible, EPR) thermal analysis. The reaction of [VO (acac) 2 ] the azo ligands ( HL n ) produced mononuclear formula (L ]H O. Results molar conductance proved that VO 2+ are non‐electrolytes fall in range 14–16 Ω‐ 1 cm mol −1 . coordination geometry is square‐pyramidal, where vanadium ion coordinated oxygen...
Trivalent Cr (III) and divalent of both Mn (II) Cu complexes containing hydrazone ligands derived from the condensation picolinohydrazide with O‐vanillin were synthesised characterized by elemental analysis, spectral magnetic measurements. The suggested octahedral structures confirmed applying DFT optimization conformational studies. thermal decomposition behaviour complex is discussed. evaluation kinetic parameters (E a , A, ∆H, ∆S ∆G) all degradation stages have been evaluated using...
Abstract The chelation behavior of some =N(1) and NH(4) thiosemicarbazones towards copper(II) ions has been investigated. isolated complexes are characterized by elemental analysis, magnetic moment, electronic, IR, ESR ms spectra, thermal voltammetric measurements. substituents on and/or the log K values ligands play an important role in complex formation. IR spectra showed that reagents HAT, HAET, HAPT, HApClPT, H2ST HBT deprotonated act as mononegative SN donors; H2SET, H2SpClPT, H2HyMBPT...
A series of perimidine derivatives (L 1–5 ) were prepared and characterized by IR, 1 H·NMR, mass spectroscopy, UV-Vis, XRD, thermal, SEM analysis. Five VO(II) complexes synthesized investigated most previous tools besides the theoretical usage. neutral tetradentate mode bonding is general approach for all binding ligands towards bi-vanadyl atoms. square-pyramidal configuration proposed complexes. XRD analysis introduces nanocrystalline nature ligand while amorphous appearance its metal ion...
