Abstract The thesis consists of three main sections plus summaries in both Arabic and English and scientific references: Chapter I (Introduction): Studies and previous research on the subject of the thesis was presented, as well as a brief overview was given for cellulose polymer and its applications for removal of some ions and pollutants from aqueous solutions. Chapter I1 (Experimental): This part includes laboratory tests and measurements have been used to prepare resins and study their properties as well as the study of behavior and capacity adsorbed on some pollutants from aqueous solutions at different conditions of time - pH - concentration - temperature. Chapter I11 (Results and Discussion): The results was presented and discussed, and divided into two parts: Part I: In this part the synthesis of copper containing modified cellulose (Cell-N-Cu) adsorbent was achieved. The adsorbent was used to purify different waters from arsenic at different experimental conditions. The adsorption behavior of the obtained samples showed high adsorption capacity as well as fast kinetics towards arsenic in their solutions. Kinetic and thermodynamic properties as well as the mechanism of interaction between As(V) and adsorbent active sites were discussed. Regeneration and durability of the loaded adsorbent towards the successive reuse were also investigated which showed high efficiency reached to 98% *1% using ammonium hydroxide without changing the properties of the resin, High arsenic uptake capability obtained from real sample results conforming the efficiency of the resin. Part 11: ENGLISH SUMMARY In this section the synthesis of modified cellulose (Cell-GTA) containing quaternary amine f~mctionality was carried out by transforming Cell-N that contains amine groups to anion exchanger by glycidyl trimethyl ammonium chloride. The adsorbent was used to adsorb phosphate and sulphate anions at different experimental conditions using batch method. Kinetic and thermodynamic properties as well as the mechanism of interaction between studied anions and adsorbent were discussed. The adsorption behavior of the obtained samples showed high adsorption capacity as well as fast uptake towards studied anions in their solutions. Regeneration and durability of the loaded adsorbent towards the successive reuse were also investigated which showed high efficiency reached to 99% and 98% for phosphate and sulphate ions respectively, using 0.1M sodium hydroxide without a change in the properties of the resin, and were also used resin to remove some of the contaminants found in the natural sample to prove the efficiency of the resin. |
