| 摘 要： | 研究了两种聚苯乙烯树脂对水中磺基水杨酸的吸附行为，同时探讨了氨基修饰聚苯乙烯树脂的吸附动力学特性．结果表明，在所研究的磺基水杨酸浓度范围内，Langmuir和Freundich吸附等温方程都能很好地描述吸附平衡数据．采用氨基修饰制备的NDA-900树脂具有较大的吸附容量和较快的吸附速率，吸附动力学符合Lagergren二级速率方程，颗粒内扩散是NDA-900树脂吸附磺基水杨酸速率的主要控制步骤，可采用HSDM模型加以描述．

| Abstract: | The adsorption of sulfosalicylic acid on two hypercrosslinked polymeric adsorbents from water was studied.The adsorption kinetic of amino modified polystyrene was also investigated.The results showed that both Langmuir and Freundlich models could simulate the adsorption equilibrium data of sulfosalicylic acid in the studied concentration range.The amino modified polystyrene(NDA-900)had high sorption capacity and good kinetic property for sulfosalicylic acid.The adsorption kinetic data fitted to the Lagergren pseudo-second order rate equation.Intrapartical diffusion was the rate controlling step and could be described by HSDM model. |
