Abstract
Ordered mesoporous carbon (OMC) was used as an adsorbent for the removal of pertechnetate (TcO4 −) anion. The maximum uptake (93 %) of TcO4 − was obtained after 60 min of contact. The adsorption of TcO4 − is almost pH-independent in very wide pH region (from 4.0 to 10.0). Maximum K d of 6.6 × 103 cm3 g−1 was found at pH 2.0. TcO4 − interacts with carboxylic functional groups present at the surface of the OMC by displacing the OH− ions with TcO4 − via ion exchange mechanism.
