| 摘 要： | 通过丙烯酰胺(AM)与二乙烯基苯(DVB)交联聚合制备聚(丙烯酰胺-二乙烯基苯)[Poly(AM-co-DVB)],并对其物理化学性质和吸附性能进行了详细研究.通过FT-IR、TG、SEM研究了该聚合物的结构与热稳定性,考察了Poly(AM-co-DVB)对刚果红的吸附性能与吸附规律,探讨了溶液p H、时间、温度对吸附过程的影响以及AM用量对聚合物吸附性能的影响.结果表明,在p H为7.25,时间为3 h,Poly(AM-co-DVB)对刚果红的最大吸附容量可达319.1 mg·g-1.其吸附等温线符合Langmuir模型,吸附动力学过程符合假二阶方程且吸附热力学表明吸附行为是自发的过程.Poly(AM-co-DVB)对刚果红具有优越的吸附性能.

| Abstract: | Poly(AM-co-DVB) was synthesized by acrylamide(AM) and divinylbenzene(DVB) via the crosslinking reaction. The microscope structure and thermal stability of Poly(AM-co-DVB) were characterized by FT-IR, SEM and TG. Congo red (CR) was used to measure the adsorptive capacity of Poly(AM-co-DVB). The effects of initial pH, contact time and temperature on the adsorption of CR on Poly(AM-co-DVB) were investigated in this work. The kinetics, equilibrium, and thermodynamics of the adsorption process were also discussed. The results showed that the maximum adsorption capacities were 319.1 mg·g-1 at pH=7.25 and contact time=3 h. The adsorption kinetics was well fitted by a pseudo-second-order model and the adsorption isotherms agreed well with the Langmuir model. The adsorption process was spontaneous process. Above all, the adsorption capacity of Poly(AM-co-DVB) on Congo red is significant. |
