Abstract: GDX-502 resin, commercially availabe in China, was an excellent adsorbent and dioxane was an excellent eluant for trace phenols in water. In this paper, the relationship between the physicochemical properties of GDXresins and the adsorption characteristics, the physicochemical properties of dioxane and the elution characteristics were investigated. Adsorption-desorption mechanism was discussed briefly by means of IR, Raman and 1H NMRspectra. The pore parameters of GDXresins were determined by mercury porosimeter.It would be raised for concentration efficiency when the dry resins were treated by a series of solvents under the experiment conditions.

Key words: Phenols, GDX resin, Adsorption characteristic
