Abstract

The ion exchange properties of αFeOOH microcrystals were investigated by titration methods. In sodium chloride media, chloride capacity in acid was due to protonation of crystal sites and sodium capacity in alkali to hydroxylation of the matrix, involving either ligand exchange of bound water for hydroxyl or acid dissociation of FeOH groups. The exchange properties are therefore amphoteric and shown to be subject to major capacity variations due to salt addition. Theory has been developed to suggest a unified explanation of the influence of salt and pH upon capacity which is well supported by experiment.
