dc.description.abstractMango seed shell can be used as an adsorbent because it contains celluloses, hemicelluloses and lignin. In this study, the activated charcoal of mango seed shell was made in two stages that were carbonization at temperature of 400oC and activation using Na2CO3 with various concentration of 2.5; 5.0 and 7.5%. The characterization result showed that activation using 2,5% Na2CO3 gave a good characteristics with 4.10% of moisture content, 2.48% of ash content, 491610 mg/kg of iodine adsorption and 14695 mg/kg of methylene blue. The activated charcoal at concentration of 2.5% Na2CO3 were contacted with various concentration cadmium solution for 24 hours and analyzed with Atomic Absorption of Spectrophotometer with efficiency of adsorption were 97.98%.en_US
