摘    要:研究啶虫脒和对甲酚在单组分、双组分水溶液中在大孔吸附树脂D201和氨基修饰的交联苯乙烯-二乙烯苯共聚体ZH202上不同温度下的吸附行为。实验结果表明,2种吸附剂对单组份两种吸附质的吸附等温线符合Freundlich方程,对甲酚和啶虫脒在2种吸附剂上的吸附过程均属放热的物理吸附过程;双组分吸附体系下,在较高平衡浓度下,呈现协同吸附现象。

关 键 词:吸附树脂  啶虫脒  对甲酚  协同吸附

Abstract:A comparison study of adsorption behaviors of acetamiprid and p-cresol on the adsorption resins D201 and ZH202 was made in single component and binary components systems by static equilibrium adsorption at different temperatures.Results showed that the adsorption was fitted by Freundlich model.The adsorption of benzoic acid on D201 and ZH202 was an endothermic process.The adsorption of both acetamiprid and p-cresol on D201 and ZH202 was an exothermic process.When the equilibrium concentration was higher,the cooperative adsorption existed.
Keywords:adsorption resin  acetamiprid  p-cresol  cooperative adsorption
