| 摘 要： | 研究了对硝基酚在四种吸附树脂(AM-1、NDA-88、NDA-99、NDA-150)上的静态吸附行为,结果表明,NDA-88、NDA-99、NDA-150三种吸附树脂对对硝基酚的吸附效果比较好。并研究了NDA-99树脂的动态吸附和脱附行为,结果显示,对硝基酚在NDA-99树脂上的吸附量为3.75 mmol/g。该树脂吸附对硝基酚后,容易脱附。用2mol/L NaOH∶C2H5OH(体积比1∶1)作脱附剂,温度328 K,体积为2.5倍树脂体积时,脱附率93%。

| Abstract: | The behavior of static adsorption of AM-1,NDA-88,NDA-99,NDA-150 resins for adsorbing p-nitrophenol were studied.The results of static equilibrium adsorption showed NDA-88,NDA-99 and NDA-150 have higher adsorption capacities.The results of dynamic adsorption and desorption indicated that the adsorption capacity of NDA-99 towards p-nitrophenol is 3.75 mmol/g.Nearly 93% desorption efficiency for the desorption agent of 2 mol/L NaOH∶C_2H_5OH(1∶1) when the volume is 2.5 times as volume of resin could be achieved. |
