Abstract
A cellulose derivative with several coordination sites for metal ions composed of cellulose powder extracted from olive industry waste and 1,2-pheneylnediamine was synthesized and evaluated as an adsorbent for metal ions from sewage. The adsorption efficiency of the cellulose amine polymer toward Fe(III) and Cd (II) was investigated as a function of adsorbent dose, concentration temperature, pH, and time .The adsorption parameters that gives the highest adsorption efficiency were determined. In addition, the cellulose amine polymer showed an excellent efficiency toward approximately twenty metal ions present in the sewage sample. The highest adsorption efficiency was at pH of about 8.3, room temperature and with 2mg/ml of polymer dose.
The cellulose amine polymer has various coordination sites amine, hydroxyl, and aromatic groups. The diversity and frequency of the coordination was the reason for the high efficiency of the cellulose amine polymer toward the metal ions. The thermodynamic analysis results (The Gibbs energy (ΔG0), enthalpy (ΔH0), and entropy (ΔS0) were calculated) supported the spontaneous adsorption efficiency of the polymer at room temperature. The kinetic study revealed that the metal ion adsorption by cellulose amine polymer was pseudo-second-order and followed the Langmuir isotherm model.
