摘　　要：制备了大孔哌啶弱碱树脂,并经过氧化氢(H2O2)氧化得到大孔氧化哌啶树脂,氧化哌啶树脂对水的亲和性增加,对苯酚的吸附性能增强,动力学吸附性能也好于哌啶树脂.树脂对环己烷中苯酚的动力学吸附符合二级动力学方程,计算得到的吸附量与实验结果相符.The piperidinyl and oxidized piperidinyl polystyrene resin were synthesized. Adsorption properties for phenol in aqueous solution and cyclohexane of the resins were measured by the adsorption isotherms and the kinetic curve. The result showed that adsorption capacities of the oxidized piperidinyl resin were larger than those of piperidinyl resin. A pseudo-secondorder equation was used to interpret the kinetic curve and the correlation is good. Qe value calculated from the equation matched well with the experiment result.
