Abstract

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
