removal of methyl orange from aqueous solution by saffron leaves as a low-cost adsorbent

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#
