| 摘 要： | 选用NDA-88、NDA-99、NDA-150、XAD-4几种吸附树脂对间硝基酚的静态吸附行为进行了研究,结果表明:间硝基酚在NDA-88、NDA-99复合功能树脂上的吸附效果较好。研究了NDA-88树脂对水溶液中间硝基酚的静态吸附等温线,并计算了吸附热力学函数,吸附行为符合Freundlich吸附等温方程,吸附量随温度升高而降低,表明为物理吸附。动力学研究结果表明:吸附速率随温度升高而增大。

| Abstract: | The adsorption m-nitrophenol on XAD-4,NDA-88,NDA-99 and NDA-150 resins was studied.The results of static equilibrium adsorption showed that bifunctional adsorption resins NDA-88 and NDA-99 have a higher adsorption capacity. The adsorption thermodynamics of m-nitrophenol on NDA-88 resin was studied.The results fit well into the Freundlich adsorption isotherm showing that the adsorption capacity goes up when the temperature goes down.The results of dynamic adsorption showed that the adsorption velocity increa... |
