Abstract

Research on metal ion biosorption of Pb (II) and Cd (II) using banana stems kepok powder (Musa Paradisiaca) in aqueous solution have been conducted. Functional group owned by the banana stems kepok powder determined by FTIR, the sides have active among others is amine (3300 – 3500 cm-1), carboxylic acid (2500 – 3000 cm-1), and aromatic (1650 – 1450 cm-1) as the absorbent metal ions in solution. The rendency of the metal ions Pb (II) and Cd (II) is absorbed by the powder banana stems kepok is determined by Atomic Absorption Spektrophotometri (AAS). The initial concentration of metal ions is used by 50 mg/L Pb (II) and Cd (II) metal ions as many as 15 mg/L, which is to obtain maximum absorption capacity (Qm) both heavy metals. The maximum absorption results obtained for the absorption of the metal ions Pb (II) is 8.18 mg/g and 2.08 mg/g for metal ion Cd (II) with conditions pH 4, biomass 0.1 g, contact time of 30 minutes and the particel size 180 μm. Based on the data gernerated can be used as biosorbent for the aqueous solution metal ions.
