摘要
以苯乙烯为单体,二乙烯苯为交联剂,甲苯和聚乙二醇为混合致孔剂,采用悬浮聚合的方法合成吸附树脂,研究树脂对苯酚的静态吸附。结果表明,当交联度50%,致孔剂:单体=1.5,甲苯:聚乙二醇400=1:1时,树脂对苯酚的吸附容量最大,达到85.16 mg/g,最佳吸附平衡时间为2 h;对树脂吸附容量影响最大的是致孔剂与单体的配比,其次依次是混合致孔剂中单体的配比和交联度。
The condition of suspension polymerization method for adsorption resins was investigated and analyzed, styrene as a monomer, divinylbenzene as a crossliking agent, toluene and polyethylene glycol 400 as mixed porogenic agent. The results showed that when the degree of crosslinking is 50%, the ratio of po- rogen and monomer is 1.5, the ratio of toluene and polyethylene glycol 400 is 1 ： 1, the resin will have a maximum adsorption capacity, it reached 85.16 mg/g, the optimum time of adsorption equilibrium is 2 h. The ratio of the porogen and monomer is the most important among all conditions. Followed by the se- quence is the monomer ratio in the mixed porogen and crosslinking degree.
