摘要
对超高交联聚苯乙烯树脂进行巯基修饰,对比大孔吸附树脂(Amberlite XAD-4)对苯酚、对甲苯酚、对氯苯酚、对硝基苯酚在水溶液中进行吸附研究。经过巯基修饰的超高交联聚苯乙烯树脂(JN-8)具有亲水性高、对酚类化合物吸附容量大的优点,该树脂可望在高浓度含酚废水治理中得到应用。
A new adsorbent （JN-8） was prepared by sulfhydryl modified. Comparing with Amberlite XAD-4, the equilibrium adsorption for phenolic compounds on the JN-8 from aqueous solutions was tested, perfect adsorption capacity was shown. Estimations of the isosterie enthalpy of adsorption, free energy and entropy of adsorption were reported, and the adsorption behaviors were reasonably interpreted.
