【摘要】 对超高交联聚苯乙烯树脂进行酚羟基修饰得到修饰后的超高交联聚苯乙烯树脂(JN-2),将该树脂与大孔吸附树脂(Amberlite XAD-4)和超高交联树脂(NDA-150)在水溶液中对苯酚进行吸附-脱附性能比较,经过酚羟基修饰的超高交联聚苯乙烯树脂(JN-2)对苯酚的吸附性能有所提高,同时脱附性能明显改善,该树脂可望在含酚废水治理中得到广泛应用。更多还原

【Abstract】 The desorptive fluent couldn’t be disposed easily because of its dilute concentration and its adherence to adsorbents in the application of resins with the method of adsorption.A comparison of properties between the polystyrene resin modified by phenolic hydroxyl group and XAD-4 and NDA150 for adsorbing the phenol in the aqueous solution were made.The results show that the performance of the resin modified by phenolic hydroxyl group is improved and this resin will be applied widely for treating the wastewater containing phenolic compounds.更多还原
