Description 52-56
A novel hypercross-linked fiber sorbent (HFS) was prepared by cross-linking polypropylene grafted styrene-divinylbenzene
(PP-ST-DVB) fiber with p-xylylenedichloride using Friedel-Crafts (F-C) reaction. A series of synthesis tests were conducted
and effects of reaction temperature, reaction time, catalyst type, and material ratio on F-C reaction were investigated. Compared
with PP-ST-DVB fiber, HFS has an excellent adsorption capacity for benzene vapor. Adsorption equilibrium for benzene vapor
on HFS was measured at 298, 323 and 348K by a static volumetric technique. Isosteric heat curve, derived from equilibrium
data, indicated that HFS has an energetically heterogeneous surface. HFS showed faster adsorption rate and higher adsorption
capacity than that of PP-ST-DVB fiber.
