摘要 | Understanding the rate and extent of Ni-63(II) sorption and desorption on/from mineral surfaces are important to predict its mobility performance in the natural environment. We herein systematically investigated the effects of pH, electrolyte cations, humic acid (HA) and temperature on Ni-63(II) sorption/desorption on/from Na-montmorillonite. The results indicated that the sorption/desorption of Ni-63 (II) on/from Na-montmorillonite were strongly dependent on pH and electrolyte cations. Desorption abilities of Ni-63(II) were Na+ approximate to Ca2+ approximate to Mg2+ at the cationic concentration of 0.2 mol/L, which was associated with the clay tactoid size. The kinetic results suggested that Ni-63(II) sorption/desorption initially increased rapidly and remained constant as time increasing. The presence of HA influenced Ni-63(II) sorption clearly and promoted Ni-63(II) desorption as a result of the dissolution of ternary surface complexes. Increasing temperature was favorable for the sorption reaction owing to the formation of strong inner sphere complexes, however, hampered the desorption reaction because of the increased stability of inner-sphere complexes or the aggregation of montmorillonite. The results are crucial to understand the physicochemical behavior of radionicicel in the natural environment. (C) 2016 Elsevier B.V. All rights reserved. |
