摘要

以环氧氯丙烷(ECH)为交联剂，碳酸钙为扩孔剂，通过反向悬浮交联技术制备了一系列具有一定粒径分布、可用于色谱法分离的大孔β-环糊精/环氧氯丙烷复合介质。电子显微镜照片显示，介质具有良好的球形度，大孔基质的孔度和含水率均高于未扩孔的基质。此外

还研究了该基质对芦丁的静态及动态吸附性能，结果表明，大孔介质的静态吸附量和吸附速率均大于未扩孔的介质。

Abstract

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.
