ABSTRACT Fenton‐like hydrogels crosslinked with imine bond were prepared for the removal of tetracycline. Initially, oxidation process carboxymethyl cellulose (CMC) was performed, and it named OX‐CMC. The confirmations then obtained using NMR FTIR analyses. degree CMC investigated in relation to reaction time, optimal time 4 h selected. In second part, a pH‐sensitive hydrogel from crosslinking between OX‐CMC chitosan. formation through confirmed by spectroscopy. By increasing ratio chitosan, swelling rate decreased. Turbidity measurements showed that higher chitosan weight resulted slower degradation acidic environments. third Fe 3 O nanoparticles concentrations 5 10 wt% incorporated into structure. TEM studies revealed spherical morphology uniform distribution within network. SEM images porous structure which composed interconnected pores hydrogel. results UV–visible spectroscopy indicated magnetic would augment as nanoparticle content increases, pH decreases, hydrogen peroxide increases.

An appropriate conventional method was employed to synthesize a new oxime-based ligand, 2,4-dihydroxybenzaldehyde oxime, and its transition metal (II) complexes with Mn Co ions. The coordination behavior, bonding nature, crystal structures of these were elucidated using spectroscopic techniques, including FT-IR, UV-Visible, powder X-ray diffraction. UV-Visible spectral analysis suggests that both exhibit an octahedral geometry. Additionally, molecular modeling through Density Functional Theory (DFT) calculations provided detailed insights into their electronic properties, stability trends, potential reactivity. optimized structural parameters, bond lengths angles, determined DFT the B3LYP functional 6-31G**, 6-311G**(d,p), LanL2DZ basis sets.
