Apstrakt:
Rare earth metals are deemed to be the materials of future due to their numerous applications including medical diagnostics, nuclear facilities, petroleum industry, etc. Multi-walled carbon nanotubes, which possess unique physicochemical properties, were evaluated as sorbents for lanthanoid gadolinium from aqueous solutions in this paper. The pH-dependent sorption behavior of Gd was studied in the pH range from 3 to 11 at room temperature (298 K). Equilibrium data over a range of initial Gd concentrations of 5−50 mg L−1 was analyzed with Langmuir, Freundlich and Redlich-Peterson models. Sorption kinetics was fitted with the pseudo-first-order, the pseudo-second-order and fractional power kinetic models.
