ABSTRACT
The influence of ionic strength, pH, and presence of ions on adsorption of Ni(II) at the FeTiO3/NaCl solution interface was investigated. Measurements of adsorption of Ni(II) ions at the FeTiO3/electrolyte solution interface was presented. ζ potential, surface charge density, adsorption density, pH50% and ∆pH10-90% parameters for different concentrations of carrying electrolyte were presented. The adsorption constants of surface hydroxyl groups were determined using numerical optimization.
