Abstract:
Charcoal is the result of the carbonization of materials that are entirely composed of carbon atoms with an amorphous structure. Activated charcoal can be synthesized from materials containing cellulose, hemicellulose, and lignin such as teak wood. The teak sawmill industry produces wood waste that can be utilized into various more useful products, one of which is activated charcoal. This study aims to make activated charcoal by utilizing teak wood waste by carbonation and then activated using KOH (chemical activation) and high temperature heating (physical activation). The parameters studied in this paper are KOH activator concentrations of 5%, 10%, 15%, and 20% and heating temperatures of 300°C, 400°C, and 500°C for two hours. Characterization of activated charcoal includes testing water content, ash content, iodine absorption capacity, and FTIR analysis. The results of activated charcoal synthesis after activation with KOH and heating show better adsorbent capabilities than before activation. Activated charcoal activated with a potassium hydroxide concentration of 20% at a temperature of 500 °C has the highest iodine absorption capacity, indicating that this activated charcoal has the highest absorption capacity.
