The use of eggshell and its membrane as adsorbents for the removal of reactive dye from aqueous solutions was investigated. The adsorption characteristics of C.I. Reactive Yellow 205 by various components of eggshells were investigated by fitting the experimental data to Freundlich and Langmuir isotherms.Eggshell membranes had a much lar ger (10 to 27 - fold) capacity to adsorb the dye than did the other components. The initial pH of dye solutions in the range 4-9 did not influence significantly the adsorption of dye by eggshell with membrane and the highest value of adsorption capacity was observed at 35?C. The extent of adsorption of the dye was related directly to the surface area of the adsorbent. The results presented demonstrate clearly that eggshell with its membrane attached is a potentially useful material to be used for the removal of reactive dyes from industrial wastewater.
