Two series of quaternary ammonium type anion-exchange resins, one having an ω-oxoalky (-CO(CH2)n-) chain and one an ω-hydroxyalkyl (-CH(OH)-(CH2)n-) chain as a spacer arm, were prepared and their sorption behavior for phenols was investigated. The resins bearing longer spacer arms could effectively sorb some bulky phenolate anions in which methyl, s-butyl or t-butyl groups were substituted at the vicinity of the phenolic hydroxyl group. The extent of sorption of phenols in an acidic medium, where phenols were sorbed physically but not by ion-exchange, changed with hydrophobicity of the phenols and was influenced by the difference in the chemical structure of spacers.
