Abstract
The adsorption of Pb (II) ions onto chitosan beads and cross-linked chitosan beads has been investigated. The epichlorohydrin (ECH) was used as a cross-linking agent. Experiments were carried out as a function of pH, stirring time, adsorbent dosage and concentration of Pb (II) ions. The experimental data of the adsorption equilibrium from Pb (II) solution correlated well with the Langmuir isotherm equation. The uptake of Pb (II) ions on chitosan beads was of 72.89 mg Pb (II)/g chitosan, while on ECH cross-linked chitosan beads, it was of 39.42 mg Pb (II)/g chitosan.
