摘　　要：以D201和氨基修饰的交联苯乙烯-二乙烯苯共聚体ZH202为吸附剂,啶虫脒和苯甲酸为吸附质,在单组分、双组分水溶液中,不同温度(288、303、313K)下进行静态吸附实验,考察树脂对吸附质的吸附行为,吸附选择性。实验结果表明,2种吸附剂在单组分和双组分体系中对2种吸附质的吸附等温线均符合Freundlich方程;通过吸附体系的热力学参数及吸附等温线说明苯甲酸在2种吸附剂上的吸附过程均为吸热过程,啶虫脒在D201和ZH202树脂上的吸附过程属放热的物理吸附过程;树脂在水溶液双组分吸附体系中,在较低的浓度时,呈现竞争吸附现象,在较高浓度时,呈现协同吸附现象。A comparison study of the adsorption behaviors of acetamiprid and benzoic acid on the adsorption resins （D201, ZH202） with that was made in single component and binary components systems by static equilibrium adsorption at different temperature, （288, 303, 313） K. The adsorption capacities and adsorption selectivity for acetamiprid and phenol in wastewater were tested. The results showed The adsorption isotherm of the adsorbates on D201 and ZH202 were conformed to Freundlich （R2=0.95-0.99）. The adsorption of benzoic acid on D201, ZH202 was an endothermic process. The adsorption of acetamiprid on D201 and ZH202 was an exothermic process by The adsorption isotherms and thermodynamic parameters of the adsorption systems. When the equilibrium concentration was lower. There existed competitive adsorption. When the equilibrium concentration was higher, the cooperative adsorption existed.
