Organic dyes constitute one of the larger groups of pollutants in wastewater released from textile
and other industries.Among 7*105 t and approximately 10,000 different types of dyes and pigments
produced world wide annually,it is estimated that 1–15% of the dye is lost in the effluents duringthe
dyeingprocess [1]. This massive influx of untreated organic chemicals into the waterways not only
introduces aesthetic concerns,but far more importantly it promotes eutrophication and adversely
affects the environmental health of theregion . It also represents an increasing environmental danger
due to their refractory carcinogenic nature [2]. From an environmental point of view , the removal of
synthetic dyes is of great concern . Among several chemical and physical methods, adsorption process
is one of the effective techniques that have been successfully employed for color removal from
wastewater.
