Preparation and Caracterization of Mangosteen Peel Activated Carbon

Abstract

The purpose of this study was to prepare and chraracterize the activated carbon from the mangosteen peel by chemical activation with zinc chloride using reflux technique. To find the optimal conditions for preparing activated carbon from mangosteen, the effect of chemical reagents:material ratio and time used to stimulate on the properties of the activated carbons were analyzed. In addition, physical and chemical properties of activated charcoal such as iodine number, moisture content, ash, volatile matter, the amount of fixed carbon and functional group by FTIR techniques were determined. The optimal condition for preparing mangosteen peel activated carbon was obtained with following conditions: time used to stimulate at 3 hour and Charcoal:zinc chloride ratio of 1:1. The highest iodine number was 820 mg/g with 1.07% moisture, 5.68% ash , 47.75% volatile and 46.57% fixed carbon content. The IR spectrum showed that the vibration of –OH, C-H, C=O functional group of mangosteen peel more intense than of activated charcoal indicate that volatile matters from activated carbon were decompose.
