Mercury Ion Removal using Chemically Modified Chitosan |
| 초록 |
To increase the uptake capacity of mercury ions, several chemical modifications of chitosan bead which is cross-linked with glutaraldehyde were performed. Among them, aminated chitosan bead prepared through chemical reaction with ethylenediamine had a high uptake capacity of about 2.3 mmol/g dry mass at pH 7. The increased number of amine groups was confirmed by IR analysis and measuring the saturation capacities for adsorption of HCl. The surface condition and existence of mercury ions on the beads was confirmed by the ESEM (Environmental Scanning Electron Microscope) and EDX (Energy Dispersive X-ray spectroscopy) instrumental analyses. Adsorption and desorption characteristics for mercury ions using aminated chitosan beads were studied. Removal of mercury species using a packed-bed column with spherical aminated chitosan material was also studied. |
