Abstract
The sorption of the dye Orange II by wool has been determined at the boiling point in the presence of various concentrations of sulphuric acid and of sodium sulphate within the range usually found in practice. Some experiments were also carried out with hydrochloric acid and sodium chloride. It is shown that the results for any one acid and salt concentration can be represented by a simple relation which has the same form for all results. Although this relation has the form of an adsorption isotherm, it remains purely empirical at present. The salt effect is readily explained on the basis of the Donnan equilibrium. The effect of acid strength is to fix the saturation value for the dye.Keywords
