dc.description.abstractFibers nut activated charcoal has been used as an adsorbent to remove cadmium (Cd2+) and lead (Pb2+) ions in solution; The activated charcoal of fibers nut was made by carbonization at 400oC for ± 2 hours and chemical activation using various concentration of H2SO4 (2.5; 5.0 and 7.5%). The characterization result showed that fibers nut activated charcoal using H2SO4 7.5% had 2,69% of moisture contain, 0.92% of ash content, 667,59 mg/g of iodine adsorption, 4,62 mg/g of methylene blue adsorption and 17,12 m2/g of surface area. Adsorption ability of the activated charcoal was analyzed in variation concentration of cadmium and lead solution for 24 hours and measured using Atomic Absorption of Spectrophotometer (AAS). The result showed the adsorption efficiency of activated charcoal of fibers nut for cadmium (Cd2+) ion was 69,58% at initial concentration 8,58 ppm and for lead (Pb2+) ion was 97,89% at initial concentration 22,80 ppm.en_US
