Optimization of durian peel based activated carbon preparation conditions for ammoniacal nitrogen removal from semi-aerobic landfill leachate

This study presents optimal conditions for preparation of durian peel based activated carbon (DPAC) for removal of ammoniacal nitrogen (NH 3 -N) from semi-aerobic landfill leachate. DPAC was prepared using chemical activation method which consisted of phosphoric acid (H 3 PO 4 ) treatment and nitrogen gasification. Optimum conditions for DPAC preparation (activation temperature, 400 °C; activation time, 2.27 h; and IR, 3) resulted in DPAC yield (21.02%) of and NH 3 -N removal (46.49%).
