Superparamagnetic Adsorbent for Removal of Uranium in Groundwater, South Korea
The feasibility of magnetic adsorbent (P-Fe-CMK-3) for the removal of uranium using
column based adsorption study has been performed. The synthesized material is efficient to
capture natural uranium from groundwater. The Phosphonate and UO2
2+ interactions were
responsible for uranium adsorption. This study confirmed the removal of natural uranium
from groundwater (with initial uranium concentration around 107 ppb) within 10 min of
contact time. However, the uptake values were not as high as compared to the values
observed in batch study due to small contact time between adsorbent and the contaminant.
Based on these results, the adsorbent material could be used in large scale treatment of
uranium contaminated groundwater and waste streams including domestic uranium filters.
