PREPARATION AND THERMAL BEHAVIOUR STUDIES OF SOME NEW POLYMERS AND THEIR USES IN METAL COMPLEXES AND.HEAVY METAL IONS REMOVAL FROM AQUEOUS SOLUTION

Abstract

The present thesis comparises three main chapters.These chapters are introduction, experimental and results and discussion. Chapter (I) represents a literature survey on the materals related to the plane of research. Chapter (II) includes the methods of preparation as well as the instrumentation and techniques used. Chapter (III) contains the data obtained and their discussion.This

Chapter is divided into three main parts:

1- Studying of the solid complexes derived from

Poly-glycidylmethacrylate bearing ethylenediamine, Poly-glycidyl­ methacrylate bearing 4-aminoantipyrine and Poly-glycidylmethacrylate bearing 2-aminothiazole. The structures for these complexes were studied by means of IR,

Electronic Spectra, DTA, TGA and Magnetic susceptibility. The study reveals that the coordination sites are ethylenediamine (for XIV), 4-aminoantipyrine(for XV) and 2-aminothiazole (for XVI) moietes

2- Studying the chelating resins

The studied chelating resin of Poly-Acrylonitryl-methylene-bis­ acrylamide with (9: 1) and (7: 3) mole ratio and bearing oxime moiety and Poly-Glycidylmethacrylate-divinylbenzene with (9 : 1) and (7: 3) mole ratio and bearing ethylendiamine moiety were studied by means of IR and thermal analysis (DTA/TG).The study indicated that the coordination sites are oxime for resins (XXIIandXXIII),ethylendiamine for resins (XXVI and XXVII )and dithiocarbamate for resin( XXVIII) moieties.
