The aim of this present work is evaluation of the effect of marble powder, which is an industrial discharge, in the adsorption of “Congo Red” dye, used in traditional industries of textile. The effect of various experimental factors; adsorbent dose, contact time (equilibrium is established after 90 minutes), dye concentration and pH media, were studied by using the batch technique. The isotherms of adsorption data were analyzed by various adsorption isotherm models such as Langmuir and Freundlich. The dye Congo Red adsorption by marble powder made have excellent performance related to the adsorption potential.
