Abstract
This study introduces three promising classes of modified chitosan
adsorbents. The new chitosan adsorbents showed high efficiency toward different
water pollutants.
The thesis comprises three main chapters:-
Chapter I (Introduction):
This chapter presents a survey on the adsorption process via chitosan as
efficient adsorbent for water pollutants, taking into consideration the survey of
recent literature including articles, books, patents and websites in this area. .
Chapter II (Experimental):
This chapter represents a description of (a) experiments used in synthesis of
different chitosan adsorbents, (b) characterization of modified chitosan adsorbents
by different analytical and spectroscopic methods such as (FTIR, SEM, XRD,
TGA, elemental analysis, water regain, dissociation in acidic medium, and point
of zero charge), and (c) studying the uptake behavior of modified chitosan
adsorbents toward three models of water pollutants (RB5, MB, and Silver ions).
Chapter III (Results and discussions):
The results can be summarized as follows:
Part I:
Two chitosan derivatives (RI, and RII) were prepared through two stages of
chitosan cross linking with amino rich compounds. The prepared adsorbents
exhibited enhanced removal efficiency towards RB5 in both acidic and basic
