Abstract
Dyes have become one of the main sources of severe water pollution as a result of the rapid development of the textile industries. Dyes, especially those with good water solubility are difficult to be removed from their effluents due to their inert properties-anti-degradability by photos, oxidants and biological agents. Besides, their low amounts in the effluents always bring on high costs of treatment. The adsorption processes have been preferred to remove dyes and its colors from waste effluents because of their low initial costs, simplicity of design and ease of operation. Recently, adsorption techniques using composite have been developed to absorb anionic and cationic dyes from aqueous solutions.
Thesis consists of three main chapters:
The first chapter is the introduction. It explains the water pollution and its sources Classification of dyes, Toxicity effects of dyes, Methods of dye removal and advantages and disadvantages of dye removal methods.
The second chapter is the materials and methods. This chapter mainly focuses on experimental reagents used for batch adsorption experiments and various characterization techniques for composites.
The third chapter is the results and discussion.
