摘要
采用悬浮法制备了一系列憎水性、高比表面积的多孔树脂,讨论了交联剂用量、致孔剂用量和组成对多孔树脂的吸油烟性能的影响。结果表明,当采用10份质量的DMA作为反应单体,采用90份质量的TRIM作为交联剂,采用100质量的致孔剂(其中甲苯为90份质量,正庚烷为10份质量)时所制得的多孔树脂的吸油烟率最大,达到0.305g/g。分别采用Langmuir和Freundlich模型方程对油烟吸附平衡数据进行了拟合分析,并探讨了吸附机理。结果表明,Langmuir方程能较好地拟合油烟在多孔树脂上的吸附平衡数据,说明该过程主要是以单分子层吸附为主,微孔填充在吸附过程中起着重要作用。
Porous resins for adsorption of oil fume were prepared via suspension polymerization. The effects of crosslinking degree, components and the dosage of porogen agent on the properties for adsorption of oil fume were investigated. The results showed that the optimum synthesis condition were 10 parts by weight of DMA, 90 parts by weight of TRIM, 90 parts by weight of toluene, 10 parts by weight ofn-heptane. The adsorptionamount of porous resin reached to 0. 305g/g. Langmuir and Freundlich models were used to correlate the experimental data, respectively. Additionally, the mechanism of adsorption for oil fume was discussed. The results showed that the experimental data were found to fit well by Langmuir model, which indicated that the adsorption process mainly based on monolayer adsorption and pore-filling was the dominating mechanism for oil fume adsorption.
