    PENGARUH SUHU AKTIVASI FISIKA PADA DAYA JERAP IODIN ADSORBEN CANGKANG BUAH KARET (Hevea brasiliensis) PERLAKUAN H3PO4
    (Elfitra, 2023-01) Rahayu, Rahayu; Linggawati, Amilia
    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.
