dc.description.abstractDurian peel biomass has been widely studied as a source of activated charcoal because it contains cellulose. This study aims to determine the adsorption capacity and adsorption kinetics of durian peel activated charcoal adsorbent in adsorbing methylene blue. Durian peel charcoal was synthesized through a carbonization process with a kiln drum followed by physical activation using microwave with variations in irradiation time, namely 8 (A8KD), 10 (A10KD) and 12 (A12KD) minutes. The adsorbent with the highest adsorption capacity in adsorbing methylene blue was sample A8KD at 75 minutes contact time of 32.05 mg g-1. Based on the adsorption of methylene blue by durian peel activated charcoal, the suitable adsorption kinetics model based on the regression value (R2) close to 1 for all samples is pseudo second-order kinetics. The adsorption constant (k2) of methylene blue on activated charcoal A12KD is the fastest among other activated charcoal with k2: 0.0105 g mg-1 min-1 and R2: 0.951.en_US
