The Properties of Activated Charcoal from Nyamplung Shell Calophyllum inophyllum Linn

The waste of nyampulng sell could be converted to activated charcoal, it is a gaseous and liquid adsorbent. The purpose of this experiment was to investigate the characteristic of activated charcoal made from nyampulng shell. Frist nyamplung shell was carbonized into charcoal, then activated by immersing in H3PO4 solution of 0%, 5% and 10%, for 24 hours and headted in retort at two level of temperatures (700 and 800 C) and two level of duration time (60 and 120 minutes) the quality of acvated charcoal were tested using SNI 06-3730-1995.The optimum condition producing charcoal was soaking in H3PO4 10% at temperature 700 C for 120 minutes. The yield of active charcoal at this condition was 52% water content 8,25% volatile matter 7,41% ash content 4,27% fixed carbon 88,32%, adsorptive capacity of iodine 839,11 mg/g and adsorptive capacity of benzene 13,65
