Abstract:
The fabrication of activated carbon made from shell of Terminalia Catappa L has
been carried out using chemical activation methods assisted by microwave
irradiation. The irradiation times was varied of 15, 20 and 25 minutes. The aims of
this study is to determine the morphological characteristics, microstructure,
surface area and the adsorption of activated carbon to the methylene blue, and to
know the influence of microwave irradiation time variations to the quality of
activated carbon as adsorbent. The results showed that the best characteristic was
the activated carbon with microwave irradiation time of 15 minutes resulted
microcrystallite dimension with Lc and La were 3.3494 and 1.0239 respectively,
surface area of 304.82 m2 / g and the methylene blue adsorption of 82.46 mg / g.
The result of methylene blue adsorption test exhibited that the time variation of
microwave irradiation affected the quality of the adsorption of activated carbon
that has been produced
