dc.description.abstractPine cone activated carbon has been used as an adsorbent to remove cadmium ions (II) and lead (II) in solution; it was made from carbonization and activation process using H2SO4 with variation concentration of 2.5, 5.0 and 7.5%. The characterization result showed that pine cone activated carbon using H2SO4 7.5% had 3.74% of moisture contain, 0.58% of ash content, 261.67 mg/g of iodine adsorption and 18.04 m2/g of surface area. Absorption ability of the activated carbon was analyzed in variation concentration of cadmium and lead solution for 24 hours and measured using Atomic Absorption of Spectrophotometer (AAS). The result showed that adsorption efficiency of unactivated pine was better i.e., 99.25% at concentration of 2.52 ppm for cadmium (II) ion and 100% at concentration of 1.53 ppm for lead (II) ion.en_US
