The adsorption of 1-hexanol and 1-butanol from water on the organically modified layered silicates, derived from magadiite by silylation with octyltrichlorosilane, was investigated. The degree of the interlamellar surface coverage of magadiite with octylsilyl groups affected the adsorptive properties. The modified magadiites with lower coverage adsorbed alcohols from aqueous solutions with lower concentrations. Both 1-hexanol and 1-butanol were adsorbed from aqueous solutions with very similar relative concentrations, suggesting that the solubilities of 1-hexanol and 1-butanol in water were correlated with the adsorption behavior. 1-Hexanol was adsorbed preferentially from a 1-hexanol/1-butanol aqueous mixture under limited conditions.
