Abstract

This study dealt with the preparation and analytical study of a type of chelating resin. This type of resin was distinguished by containing a ligand of the type of aromatic Schiff bases (5A-T) by reacting the aromatic amine (5-aminoisopthalic acid) with terephthaldehyde. The prepared Schiff base was identified using infrared FT-IR, 1H-NMR, 13C-NMR, and precise element analysis technology. The prepared Schiff bases were converted into azomethine-amide resin P5A-T by reacting the ligand (5A-T) with the diamines (4, 4-oxydianiline). The prepared resin was characterized using infrared spectroscopy. The study also included the preparation of magnetic zinc iron oxide (ZnFe2O4) by covalent deposition method and its inoculation with the prepared resin P5A-T. ZnFe2O4 and the composite resin were diagnosed using several techniques, including scanning electron microscopy (FE-SEM), the particle size is (22 nm) for zinc iron oxide and (36 nm) for the composite magnetic resin. In addition, X-ray diffraction (XRD) technology was used in the diagnosis process, and the results confirmed the validity of the prepared composition. In addition, the magnetic properties of ZnFe2O4 and the prepared resin were studied and the composite resin showed superior magnetic behavior. The Malven Zetasizer device was used to measure the zeta potential. The last part included a study of the analytical efficiency in the adsorption of some heavy element ions (Ni+2, Pb+2, Cu+2) using the batch method. The loading capacity of the prepared resins was studied under various conditions such as acid function and treatment time. The order of selectivity was Pb(II) > Cu(II) > Ni(II).
