The purpose of this study is to suggest an efficient process ,Adsorption ponceau4r using peanut shell and modified into a novel magnetic nano adsorbent by co precipitating it with Fe3O4were studied as adsorbent by batch method. The effects of some important physical and chemical parameters such as the initial dye concentration,sorbent dosage,contact time,tempreture and pH on the sorption of selected dye introduced adsorbent were investigated.
