Modification of Cassava Residue for the Adsorption of Pb(II) Ion from Aqueous Solution
Abstract
In this work, the use of cassava residue xanthate (CRX) as adsorbent for the removal of lead(II) ion from aqueous solution was investigated. The CRX was prepared by Xanthate method. Fourier Transform Infrared Spectroscopy (FTIR) and Zeta potentials were used for characterization the prepared CRX. The parameters effective the experiments were studied including type of adsorbent (cassava residue (CR) and modified cassava residue), pH, and initial lead (II) ion concentration. It was found that the optimum condition was 100 mg/L of initial concentration lead (II) ion, 0.50 g/L of XCR adsorbent dosage with pH of 5.0 and contact time of 30 min, the percentage of adsorption was 80.74. The adsorption behaviors of lead (II) ion on CRX fit both the pseudo-second order kinetic model and the Langmuir isotherm model. The maximum adsorption capacity from the Langmuir isotherm equation was 250.00 mg/g. Thus, the cassava residue xanthate has the potential to be used as the adsorbent for the removal of heavy metals in waste water.
