Attenuation of radiotoxic ions from aqueous solutions using immobilized iron-oxide sand |
| 초록 |
The present work deals with the immobilization of iron oxide nano-particles onto the surface of natural sand. The synthesized material was employed for the efficient removal of radiotoxic cesium and strontium from aqueous solutions. The surface morphology and elemental compositions of immobilized iron-oxide sand as well as bare sand were obtained by SEM-EDX analysis. Moreover, the materials were characterized by XRD and FT-IR analyses. Reasonable amount of iron was loaded onto the sand surface and the immobilized iron particles were stable within a wide pH ranges i.e., pH 3.0 to 10.0. Batch experiments showed that increasing the sorptive pH significantly favours Cs(I) and Sr(II) removal and the equilibrium state sorption data under the concentration dependence study reasonably fit to Langmuir and Freundlich adsorption isotherm. Moreover, the breakthrough data were collected and the non-linear Thomas equation was utilized to determine the loading capacity of Cs(I) and Sr(II) using column packed with immobilized iron-oxide sand. |
