Abstract

A thesis consists of three parts adding to Arabic and English summary and references. The first chapter (Introduction: Review of recent study which related to the subject of this a thesis and short
note of polymer cellulose and its chelat and its application in removing of
some metals and pollutants from aqueous solutions.
The second chapter (Experimental and lab measurements):-
This chapter has the experiments and measurements which used for
preparations of resin and study its properties. Also study the adsorption
capacity towards heavy metals and some pollutants from their aqueous
solutions at different conditions such as time, pH, concentration of metal
ions and temperature.
The third chapter (Results and Discussions):-
In this chapter presentation of results and discussion and divided in to two
parts:
Part I:
In this part preparation of resin by polymerization of glycidyl methacrylate
on the surface of cellulose by adding Bz2O2 as initiator and then loaded by
amine groups used diethylenetriamine. The ability of the resin adsorption
has been study towards the copper and mercury from their aqueous
solutions. The resin show high adsorption capacity and fast kinetic. Also
studying the factor affecting the adsorption behavior such time, pH,
concentration of adsorbed anions and also determined the thermodynamic
and kinetics reactions of resin.
Summary
Regeneration has been occurred by acidified thiourea by H2So4, which
appear high reactivity reach to 95% without any change in resin properties.
Also used the resin in removing some pollutants present in real samples
from Nile water, ground water, sewage water and waste water from batteries
factory to confirm the efficiency of resin.
Part II:-
In this part, preparation of resin by polymerization of GMA on cellulose in
presence of Bz2O2 as initiator and then loaded by amine groups used
diethylenetriamine and then convert to ion exchange by glycidyl
trimethylammonium chloride and studying adsorption towards chromate and
molybdate from aqueous solutions. Studying the better conditions for
adsorption of these anions with ion exchange at different conditions such as
time, pH, and concentration and determination of thermodynamic and
kinetics. Regeneration also studied by use suitable solution NaOH for
adsorption of chromate and molybdate, which give high efficiency without
change in properties of resin. Regeneration has been occurred by 0.1 M
NaOH solution as a desorption agent. The ACGA obtained has good
durability for four cycles.
