Abstract

processed as activated charcoal using charcoalization and activation processes because it contains lignin of 33.54%.Activated charcoal is used as an adsorbent, gas purification and a catalyst. This study aims to determine the effect of thetemperature of charcoalization on the quality of activated charcoal based on SNI 06-3730-1995 standard. With thevariations of charcoalization temperature of 300°C, 400°C, 500°C, 600°C, and 700°C for 1 hour with material mass of360 gram for each temperature variation, chemical activation using sulfuric acid of 7% for 1 hour and activation ofphysics with the temperature of 600°C for 1 hour. The best results showed at a temperature of 500°C with rendement of21.39%, water content of 12.78%, ash content of 12.78%,, volatile matter content of 17.18%, the absorption of iodine1096.59 mg/g. Moreover, an analysis using SEM pores before activation was 2.92 μm and after activation was 15.41 μm.Activated charcoal before and after activation experienced enlargement of pores of 12.49 μm. As a result, the absorptionwill be greater when compared with the charcoal of fruit rubber shells without activation.
