孔径均匀、可控的大孔吸附树脂的制备及筛分性能的研究

改变传统的由非良溶剂致孔合成大孔吸附树脂的方法,设计合成了一系列孔径均匀且具有筛分作用的新型吸附树脂,通过改变起始共聚物的交联度,可以调控树脂的孔径.混合样品的分析结果表明,对于分子尺寸不同的苯酚、芦丁、人参皂甙Re具有明显的筛分分离效果.在苯酚与芦丁的混合样品及苯酚与人参皂甙Re的混合样品中,小分子苯酚的去除率分别达到88.44和73.09.

Preparation and Sieving Property of Adsorbing Resin with Homogeneous Pore Diameter and Controllable Large Pore

The new type polymeric adsorbing resin with homogeneous pore diameter and sieving controllable large pore was synthesized. The method of synthesis of the resin was different from that of the normal macro porous polymeric adsorbent. By altering the initiative cross-linking degree, the pore diameter of the adsorbent could be controlled. The sieving effect of the resin was represented by separating different molecules with different sizes, such as phenol, rutin and panaxtriol Re. For the mixture of phenol and rutin and the mixture of phenol and panaxtriol Re, the ratio of wiping off phenol is 88.44% and 73.09%, respectively.
