Abstract
This thesis includes three chapters. The first of which is a review of the literature on the different extraction methods of cellulose from different marine sources and the detection cellulose methods in different seaweeds. Also, includes variety of chemical modification of cellulose, reactions, grafting, crosslinking, and composites formation with nano-materials and its application for water treatment.
The second is discussion of the results we got which includes three parts the first one is extraction of cellulose from mangroveAvicenniamarina roots pulp and acetylated this extracted cellulose, then form nano composite with nano-manganes dioxide which was prepared by reduction of potassium permanganate with ethanol. The grafted co-polymerization of this composite by acrylamide monomer was occurred to introduce ethylenediamine, diethylenetriamine, triethylenetetramine and tetraethylenepentamine. These amines can make complex with different heavy metals soluble in water in addition to nano-manganes dioxide removal. So, these compounds were used for extraction of Cu(II), Cd(II) and Pb(II) from water after the optimization of pH, shaking time and mass dosage, also these were applied to real water samples (sea water, tap water and wastewater) using multistages micro column. Two models were used for determinig adsorption process. These compounds were characterized by fourier transform infra-red, thermal gravemetric analysis, scanning electron microscope and EDAX.
