A series of novel macroporous β-CD-EP(M-CD-EP) composite matrix with a suitable particle size distribution for chromatography were prepared by the reversed-phase suspension crosslinking technique using epichlorohydrin as a crosslinking agent and calcium carbonate as a porogenic agent.For comparison
the homogeneous(H-CD-EP) beads were also fabricated without calcium carbonate.The photographs got by scanning electron microscope indicated that the M-CD-EP particles have spherical appearance with some “pits” on the surface.As a result
the porosity and water content of M-CD-EP matrix are higher than that of H-CD-EP matrix.Besides
the static and dynamic adsorption performances of the matrices for rutin were also studied.The results showed that more rutin was adsorbed and there was higher adsorption rate for M-CD-EP medium than for H-CD-EP one.The pore diffusivity of rutin in the M-CD-EP beads is two to three times as big as the H-CD-EP beads.
