摘要: 通过改变苯乙烯-二乙烯苯共聚物的交联度和使用不同结构的二乙烯苯,合成了树脂Ⅰ-Ⅵ,在工业二乙烯苯共聚体系中加入少量丙烯酸甲酯合成了树脂Ⅶ;交联聚苯乙烯经Friedel-Grafts酰化反应在其苯环上引入乙酰基制备了树脂Ⅷ。用物理技术和化学方法表征了树脂的结构。树脂对叶绿素铜的吸附量不仅与其二乙烯苯含量有关,还与二乙烯基的位置(间-,对-)异构有关,树脂骨架极性的增加,不利于树脂对叶绿素铜的吸附。

Abstract: The macroporous polymeric adsorbents(-Ⅶ)were synthesized by suspension homopolymerization of divinylbenzenes wtih various purities (56%-97.5%) or copolymerization of divinylbenzenes and styrene as well as a small amount of methyl acrylate in one example.The adsorbent(Ⅷ)was obtained by Friedel-Crafts acetylation of the crosslinked polystyrene-type resin(Ⅱ).The structural characterization of the adsorbents(Ⅰ-Ⅷ)were carried out by means of physical techniques and chemical methods.Their adsorption capacities to chlorophyll were determined in a batch test.The results showed that adsorbentsⅠⅧ could adsorb chlorophyll copper and their capacities depend on porous structures, specific surface areas, and polarities of these adsorbents.

Key words: Crosslinked polystyrene, Adsorbed resins, Divinylbenzene, Chlorophyll
