Adsorption using carbon is one of most simple and economical technique for the purification of water. Carbon acts as an efficient and cost-effective adsorbent for the removal of pollutants from wastewater. In this work, carbon was produced using Raphanus Sativus leaves through carbonization method at different temperatures i.e. 2500C, 3500C and 4500C. Effects of activation time and activation temperature was analyzed during carbon preparation. Characterization of synthesized carbon was carried out by XRD, SEM, EDX and BET. Moreover, the resultant Carbon was used as an adsorbent to remove phosphates and malachite green oxalate dye from aqueous medium. Different parameters like effect of PH, contact time adsorbent dose, concentrations of phosphates and malachite green dye were studied. It was observed that by increasing adsorbent dose, time and by decreasing concentrations, adsorption increases till all active sites of carbon is used. Thermodynamics and kinetics study is under investigation and the result will be discussed at conference.
