Abstract
The rubber fruit shell (CBK) (Havea brasiliensis) is waste product from rubber
plantations that has carbon sources so can be used as adsorbent. In this study The rubber fruit
shell chemically activated use activator H3PO4 10% produce low iodine adsorption capacity,
then activated physically with variation in temperature (250; 300; 400)ÂșC and 15 minutes. The
results of the characterization of iodine adsorption capacity (AACBK) were obtained in
AACBK 250-15 sebesar 875,92 mg g-1 , AACBK 300-15 sebesar 1,074,35 mg g-1 , AACBK
400-15 sebesar 1.271,31 mg g-1. The character of rubber fruit shell activated charcoal (AACBK)
produced by the adsorption capacity of iodine meets the standards as an adsorbent in
SNI 06-3730-1995 regulations.
