Abstract: The title resin was synthesized and the adsorption isotherms of phenol from cyclohexane solution were measured. Values of isosteric adsorption enthalpy, adsorption Gibbs free energy and adsorption entropy were calculated. These values implied a hydrogen-bonding adsorption mechanism. Furthermore, difference of adsorption property for phenol and o-nitrophenol from cyclohexane solution was studied, and the result was in accordance with the hydrogen-bonding mechanism.

Key words: Macroporous cross-linked poly(N-methyl-N-p-vinylbenzylacetamine) resin, Non-aqueous system, Phenols, Hydrogen-bonding, Adsorption mechanism
