dc.description.abstractOrange peel was investigated as adsorbent in activated carbon with variation of sodium hydroxide concentration (2.5%, 5%, and 7.5%) . The characterization result showed that activated carbon of orange peel with 7,5% sodium hydroxide have 1.2% of moisture contain, 3.96% of ash content, 659.7703 mg/g of iodine adsorption and 39.125 m2/g of surface area. The presence of functional groups in orange peel activated carbon was confirmed by FT-IR Spectroscopy. Orange peel activated carbon was reacted with variation of concentration cadmium and lead solution for 24 hours and analyzed with Atomic Adsorption of Spectrophotometer. It was found that adsorption efficiency for cadmium and lead was 98.09% and 99.66% respectivelyen_US
