Eucalyptus pellita Actived Carbon for Fe Absorption Effect of Carbonization Temperature and Concentration of KOH Activator

Abstract

Eucalyptus pellita bark is a waste from the pulp industry that can be used as a raw material in activated carbon manufacturing because it contains high enough cellulose, hemicellulose, and lignin. This study aims to determine the effect of various carbonization temperatures and KOH activator concentrations on Fe absorption in water. Making activated carbon procedure consisted of dehydration, carbonization, and activation. Furthermore, the analysis of activated carbon characteristics was based on Fe absorption. The variations of this study consisted of carbonization temperature, 250oC, 300oC, and 400oC, and variations of KOH activator concentrations, 0.2 N, 0.7 N, and 1.2 N. The best-Eucalyptus pellita bark activated carbon obtained for carbonization temperature at 350oC and an activator concentration at 1.2 N with the value of Fe absorption was 95.343%.
