Popis:	We have studied chemical equilibrium between functionalized carbon nanofibers and an aqueous ZrOCl2 or ZrOSO4 solution and evaluated the sorption capacity of the nanofibers as a function of Zr concentration, solid: liquid (S: L) ratio, solution pH, and the degree of nanofiber functionalization. The results demonstrate that the equilibration time at S: L = 1: 10 and 1: 2 is 10 and 30 min, respectively, and that the sorption capacity increases with increasing solution pH or Zr concentration and with decreasing S: L ratio and exceeds 2.0 mg ZrO2/mg of the sorbent under certain conditions. A saturated sorbent after drying can be used to fabricate nanofiber-ZrO2 composites.
