摘　　要：研究了以不同基团修饰的吸附树脂对水中邻苯基苯酚的吸附行为,考察了吸附温度、时间、溶液浓度和吸附剂的种类对邻苯基苯酚的吸附效率的影响.结果表明:实验条件下,化学修饰的吸附树脂对邻苯基苯酚较佳的吸附温度为303K,具有丰富羰基基团修饰同时具有合适孔径的吸附树脂及更好的吸附效果,吸附等温线更符合Langmuir方程,吸附动力学符合Lagergren准一级动力学吸附方程.The adsorption of 2-phenylphenol in water onto resins modified with different functional group were studied,and the influence on the type of resin,adsorption temperature,adsorption time and initial concentration of o-phenylphenol was investigated.The results shows that the adsorption temperature of 303 Kis a good choice and the hypercrosslinked resins coneained abundant carbonyl group and matched pore diameter with good adsorption capacities for 2-phenylphenol in testing condition.Adsorption data was preferably fitted into Langmuir equation and all the dynamics adsorption equations of o-phenylphenol onto six adsorbents fit the adsorption pseudo-first order process perfectly.
