Spherical absorbent resins for benzene series were synthesized by suspension polymerization. The dependence of absorbency

crosslinking density and gel fraction of resins on crosslinker dosage was studied. The effects of crosslinking structure on absorption kinetics and release kinetics were investigated. Scanning electron microscope was used to observe the morphology of the resins. Gel fraction and crosslinking density kept increasing while a peak absorbency was observed with increasing crosslinker dosage. With the increase of crosslinking density

absorption rate and release rate of the resin for toluene reduced gradually

and absorption kinetic constant and diffusion coefficient decreased. Absorption kinetics of the resin for toluene fitted the quasi first order equation. A simple release kinetics equation was obtained

by which the release behavior could be well described. Crosslinking structure of the resin was stable. The size

morphology and absorbency of the spherical absorbent resin did not change obviously after 10 times recycle and reuse.
