From: Competitive sorption of Ni and Zn at the aluminum oxide/water interface: an XAFS study
Kinetics of Ni and Zn sorption onto γ-Al2O3 from 0.8 mM Ni or Zn solutions at pH 7.5. a Ni sorption onto γ-Al2O3 in the single-sorbate system; b Zn sorption onto γ-Al2O3 in the single-sorbate system. c Ni sorption onto γ-Al2O3 in the binary-sorbate system; d Zn sorption onto γ-Al2O3 in the binary-sorbate system. A constant ionic strength of 0.1 M NaNO3 and a solid/solution ratio of 2.5 g l−1 was used. The last sample of each experiment was collected and analyzed by EXAFS
