Study of 63Ni(II) sorption on CMC-bound bentonite from aqueous solutions

Interaction mechanism of radionickel on Na-montmorillonite: Influences of pH, electrolyte cations, humic acid and temperature

“…The sorption percentages of 63 Ni(II) on Na-montmorillonite were in the sequence of Na + > K + > Ca 2+ > Mg 2+ . The results could be easily explained by the competition adsorptive capacity of different positive ions with 63 Ni(II) [32]. Cations in solution competed for interaction with the limited surface functional groups of Na-montmorillonite.…”

Interlamellar Space Configuration under Variable Environmental Conditions in the Case of Ni‐Exchanged Montmorillonite: Quantitative XRD Analysis

“…On the other hand, the interlayer water organization in presence of exchangeable heavy metal cations (i.e., Ni 2+ ) initiates the necessity to monitor the behavior of this barrier according to several climate changes and environmental factors that may affect the clay matrix in order to predict its short-and long-term performance. All earlier works report the importance and the performance of clay minerals especially montmorillonite to retain Ni(II) [17][18][19][20][21][22][23][24][25][26][27] ions. In the present study, an investigation of the effect of the relative humidity variations on the hydration performance of a Ni-exchanged montmorillonite is achieved.…”
