The adsorption of Congo Red from aqueous solutions onto cellulose and cotton fibres has been carried out to investigate `Sorption'. Both substrates were given various treatments and the effect of such treatments was examined towards sorption. Two types of isotherms were observed namely, H- and S-type. A more specific form `HA' leading to 'flatewise' adsorption on cotton was identified. The electrolytes strongly influence the sorption capacity of Congo Red on both fibres which is interpreted on the basis of Donnan Theory.
