PREPARATION OF NEW COMPLEXES OF METHYL METHACRYLAT WITH POLYVINYL ALCOHOL AND STUDY OF SOME ENVIRONMENTAL APPLICATIONS

Abstract

A new copolymer from Methyl methacrylate and polyvinyl alcohol [methyl-5-hydroxy-2-methylhexanoate] and its complexes were synthesized for some metals (Cr⁺³, Mn^{+ 2}, Fe^{+ 3}, Co^{+ 2}, Ni^{+ 2}, Cu^{+ 2}, Zn^{+ 2}, Cd^{+ 2}). This ligand and its metal complexes were characterized using (FTIR) spectral, UV-Vis spectroscopy, conductivity, magnetic moment, and Thermo Gravimetric analysis. The nanoparticles for two complexes were characterized using x-ray diffraction, scanning electron microscope, and atomic force microscope. Zeolite 5A was prepared from local kaolin by hydrothermal preparation, then characterization, and used as a supporting material with prepared copolymer as a composite to remove several metals from polluted water taken from industrial water electric power stations in Dora and South of Baghdad. Trace concentrations of these metals were estimated before and after applying the prepared copolymer by atomic absorption spectroscopy. The removal using composite materials is significantly more effective, with the concentration recorded as very low and the concentrations of some metal ions like Fe⁺², which completely disappeared from polluted water according to a polluted water analysis before and after using the produced compounds.
