WITHDRAWN: Magnetic polyazomethine-amide nanocomposites: Synthesis and characterization, and their application

Abstract

The preparation of the Schiff base 5A-O ligand in this study was through an interaction between 2-Hydroxy-3-methoxybenzaldehyde and 5-aminoisophthalicacid, and the product was characterized by several techniques such as 1-HNMR, 13 CNMR, mass spectrometry and elemental analysis. With good yield (85percent) the monomer derivative reacted with 4.4′-diminodiphenyl ether and triphenylphosphite (TPP) to form an aromatic polyamide (P5A-O) These polymers were easily soluble in NMP, N, N-dimethylacetamide, dimethylsulfoxide, and pyridine, among other solvents. The polymerization reaction was carried out by using the polymerization process to modify the surface of magnetic nanoparticles (Fe3O4 MNPs). To confirm the composition of the prepared nanocomposite, various analytical techniques such as field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray, and vibrating sample magnetometer (VSM) tests were used. The effect of the polymerization process of the synthetic polymeric on the surface of a sphere shape was observed by FE SEM photographs. The Brunauer Emmett–Teller equation was used to determine the surface area of a magnetic polymer. The elimination of Ni(II) and Fe(III)ions from aqueous solutions using this novel magnetic nanocomposite was compared under a number Experimental conditions and criteria, including pH, adsorbent dose and touch time for removal of heavy metals. Antioxidant operations in vitro, such as DPPH radical scavenging, were analyzed and revealed that poly azomethine-amide possessed significant antioxidant properties.
