Abstract:
The researchstudied the effect of variations in chemical activation time toward adsorption
rateof activated carbon from Eucalyptus Pellita wood. Eucalyptus Pellita wood used was the
inside part of wood which was about 2 cm from the outer portion wood. The first process
ofEucalyptus Pellita wood becoming activated carbon was done by the conventional
carbonization process for 1.5 hours and continued by the process of chemical activation using
KOH activator with variations of activation time 15, 20, 25 hours, and aided by microwave
irradiation. Characterization of surface morphology showed that the activation time of 25
hours produced the most pores and supported by the pore surface area of activated carbon of
331.058 m2 / g and the maximum adsorption rate of 89.26 mg / g. The results showed that the
chemical activation time variation affects the physical properties of activated carbon made
ofEucalyptus Pellitawood.
