AI Article Synopsis
- Ni(II) and Cu(II) complexes were created using a specific ligand (2-pyridinecarboxaldehyde thiosemicarbazone) and different anions (like Cl-, NO3-, and SO4^2-).
- These complexes underwent thorough characterization through various techniques including elemental analysis and spectral studies, revealing high-spin configurations and distinct geometric structures (octahedral for Ni(II) and mostly tetragonal for Cu(II)).
- The synthesized compounds were also tested for their effectiveness against harmful fungi and bacteria in laboratory conditions.
Article Abstract
Ni(II) and Cu(II) complexes having the general composition [M(L)(2)X(2)] [where L=2-pyridinecarboxaldehyde thiosemicarbazone, M=Ni(II) and Cu(II), X=Cl(-), NO(3)(-) and 1/2 SO(4)(2-)] have been synthesized. All the metal complexes were characterized by elemental analysis, molar conductance, magnetic moment, mass, IR, EPR and electronic spectral studies. The magnetic moment measurements of the complexes indicate that all the complexes are of high-spin type. On the basis of spectral studies an octahedral geometry has been assigned for Ni(II) complexes whereas tetragonal geometry for Cu(II) except [Cu(L)(2)SO(4)] which posseses five coordinated geometry. The ligand and its metal complexes were screened against phytopathogenic fungi and bacteria in vitro.

A novel nanocomposite magnetic hydrogel was synthesized based on κ-carrageenan, acrylic acid, and activated carbon as an absorbent for removing heavy metal ions from aqueous solution. FT-IR spectroscopy, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and vibration sample magnetometer (VSM) were employed to confirm the structure of the nanocomposite hydrogels. The effects of contact time, pH, particle size, temperature, and metal ion concentration on the metal ion adsorption were investigated.

The Schiff base metal complexes containing the transition metal ions Co(II), Ni(II) and Cu(II) were synthesized using their nitrate and acetate salts. An octahedral environment encircling metal complexes has been demonstrated by the findings of multiple spectroscopic approaches that were employed to demonstrate the structure of the metal complexes. The Coats-Redfern method of thermal analysis was employed to carry out the kinetic and thermodynamic calculations.

Fast-paced global industrialization due to population growth poses negative water implications, such as pollution by heavy metals. Phytoremediation is deemed as an efficient and environmentally friendly alternative which utilizes different types of hyperaccumulator plants known as macrophytes for the removal of heavy metal pollutants from contaminated water. In this study, the removal of Cu(II), Ni(II), Pb(II), and Cd(II) heavy metal ions contaminated water was studied by using an aquatic plant, Persicaria amphibia (L.

This research focused on the design and characterization of two new transition metal complexes, NiMetPhe and CuMetPhe, derived from methionine (Met) and 1,10-phenanthroline (Phe), coordinated with Ni(II) and Cu(II) ions, respectively. Structural elucidation through analytical techniques, conductivity, elemental analysis, FTIR spectra, electronic spectra, magnetic moment, mass spectra, and thermal degradation, confirmed their octahedral geometries with the formulas [Ni(Met)(Phe)(Cl)(H₂O)] and [Cu(Met)(Phe)(Cl)(H₂O)]. Thermal analysis revealed their stability and decomposition patterns, whereas density functional theory (DFT) calculations validated the structures and provided insights into quantum chemical parameters, such as highest occupied molecular orbital-lowest unoccupied molecular orbital (HOMO-LUMO) energies, molecular orbitals, and electronic distributions.

The recovery of Co(II), Mn(II), Ni(II), and Cu(II) from black mass e-waste solutions through cellulose nanofibers (CNFs) and nanocrystals (CNCs) was investigated. These materials were synthetized by TEMPO-oxidation followed by high-pressure homogenization, and acid hydrolysis, respectively. The NC characterization included the measurement of consistency, cationic demand, carboxylic content, dissolved amorphous cellulose, and transmittance at λ = 600 nm.
