The ability of Saffron leaves to removal methyl orange (MO) from aqueous solutions has been examined in this work. Batch adsorption studies were carried out at different contact time, initial concentration (50–150 mg/L) and adsorbent dose (0.02–0.10 g) on the removal of methyl orange (MO) at the temperature of 25 ◦C.The results indicated that percentage of dye removal increased with increasing contact time as well as the adsorbent dose. The results also indicated that increasing the initial concentration of methyl orange resulted in a gradual decrease in the percentage of dye removal. The optimum adsorbent dose was determined for dey adsorption for 0.06 gr. Therefore, the Saffron leaves waste was shown to be a very efficient and low-cost adsorbent, for removing dyes from industrial wastewaters.
