摘要: 以9种一元酚为吸附质,系统讨论了GDX-502和二氧六环的理化性质对酚类富集及洗脱性能的影响。结果表明,GDX-502使用前的溶剂预处理具有净化树脂和改变树脂的孔结构的双重功能,用本文方法对GDX-502进行溶剂预处理,可使树脂获得有利于酚类富集与洗脱的孔结构,该树脂对水中酚类的富集作用是以Van der Waals力和较氢键弱的π-键合作用力为基础的物理吸附,而二氧六环洗脱酚类的实质是氢键作用。

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
