Specific adsorption of halogen anions on hydrous γ-Al2O3 Original Research Article

The paper reports results of a study on the specific adsorption of F−, Cl−, Br−, I−, ClO3−, BrO3−, IO3− and IO4− on hydrous γ-Al2O3. The isotherms of the anion adsorption and the adsorption dependencies on pH and the ionic strength of the solution have been determined under the equilibrium conditions. According to the degree of affinity to γ-Al2O3, the anions can be ordered as: I−
