One of the most common plantation biomass wastes is palm fronds, which will decompose without further processing. Lignin, hemicellulose, and cellulose contributed 31.7 percent, 33.9%, and 17.4%, respectively, of the chemical compounds found in oil palm leaves. The purpose of this study was to determine the ability of activated carbon to adsorb copper and lead metals, as well as to calculate its kinetics and adsorption capacity. Activated carbon with a certain amount is added to 50 ml of copper and lead metal solution for a certain time. The results obtained after the adsorption process were analyzed using Atomic Absorption Spectrophotometry (AAS). From the results of AAS analysis, it was found that activated carbon with a mass of 1.5 g and a contact time of adsorption for 40 minutes was the most effective in reducing the concentration of copper and lead metals. Copper metal adsorption follows Freundlich adsorption isotherm model while lead metal follows Langmuir adsorption isotherm model. The adsorption kinetics pattern of copper and lead metals follows second order kinetic adsorptions.
