In this study ,the adsorption of an industrial blue dye was investigated by using pomegranate peel in different size . The effect of the process parameters such as , contact time ; adsorbate concentration pH) and (temperature ) are reported . "Nearly 2-3 hr of contact time are found to be sufficient for the adsorption to reach equilibrium" (Abetter fixation was obtained at acidic pH (2) and room temperature 25◦C.
