摘　　要：研究了水杨酸修饰的超高交联吸附树脂SYS对不同温度下水溶液中邻氯苯酚的静态吸附,并探讨了SYS树脂对邻氯苯酚的吸附热力学的特征.结果表明,邻氯苯酚在水杨酸树脂上的吸附符合Langmuir和Freundlich等温吸附方程,其动态吸附过程可分为大中孔区和微孔区的吸附两个阶段,两个阶段都符合准一级动力学吸附方程.Studies on the adsorption thermodynamics and kinetics of 2-chlorophenol by SYS resin modified by salicylic acid was carried out through static experiments at at different temperature. And the adsorption data was fit for the Fretmdlich and Langmuir adsorption isotherm. The result shows the adsorption of 2-chlorophenol on SYS resin is an exothermic sorption process which rims spontaneously, and the adsorption of 2-chlorophenol on SYS resin is carried out in two regions of the macropore/mesopore region and the micropore one while the adsorption rates in the two regions both fulfil the first order kinetics.
