1. Introduction
Growing concern for public health and environmental quality has prompted a special interest in developing and implementing various materials and methods for removing the toxic organic and inorganic pollutants from water. Dyes from the effluent of textile industries are the major sources of water contamination [1]. Apart from the aesthetic desirability of colored streams resulting from dye waste, the presence of dyes in water reduces light penetration and hinders photosynthesis in aquatic plants [2]. Some dyes and their degradation products in surface water are reported to be highly carcinogenic [3]. It is, therefore, essential to treat the dye effluents prior to their discharge into the receiving water. The most commonly used methods for color removal are coagulation, flocculation, biological oxidation, chemical precipitation and activated carbon adsorption [4].
