Description

The adsorption of ultra-trace levels of polonium on Luffa cylindrical biochar fibers has been investigated in deionized water and seawater samples prior and after surface modification (Ag-coating) of the adsorbent. The effect of pH on the sorption efficiency (Kd values) indicated that pH, which governs the solution chemistry of Po(IV), affects to a large degree the adsorption efficiency and that Ag-coating of the surface results in significantly higher Kd values. The modified adsorbent presents enhanced removal efficiency for 209Po even from seawater samples indicating the usefulness of the modified biochar fibers for the treatment of polonium contaminated waters.
