Abstract:
Physical activation temperature affects the adsorptive power of activated charcoal in
rubber fruit shells. The higher the physical activation temperature, the more
hydrocarbon compounds and organic compounds are lost in the physical activation
process. In this research, the effect of physical activation temperature on the character
of activated carbon synthesized from KOH-activated rubber fruit shells was studied. In
this research, activation of rubber fruit shells using 15% KOH was followed by physical
activation with temperature variations of 250°C, 300°C and 400°C. Several characters
of activated carbon are determined including iodine adsorption capacity according to
SNI no. 06-3730-1995. The results showed that the yield of activated carbon decreased
as the physical activation temperature increased. The results showed that the adsorption
capacity of iodine increased as the activation temperature increased. AA400 has the
highest iodine adsorption capacity of 1176.782 mg g-1.
