چکیده

This research work investigates the efficiency of H3PO4and KOH impregnated jackfruit leaf powder based carbon as adsorbent to remove Ni from wastewater. The removal characteristics of Nickel using both the adsorbents were investigated under various operating variables like contact time, adsorbent dosage, initial metal concentration, solution pH, temperature and stirring speed. The results showed that the H3PO4impregnated jackfruit leaf powder based carbon is a better adsorbent than the KOH impregnated adsorbent. The experimental results were found to fit well with langmuirand freundlich isotherms.The maximum adsorption capacity of theH3PO4impregnated adsorbentwas found to be 62.98 mg/g and that of the KOH impregnated adsorbent to be 54.66 mg/g.
