摘要
通过具有稳定杯式构象的环氧丙基杯[6] 1,4 冠4与壳聚糖发生接枝交联反应,合成了新型杯[6]冠醚接枝壳聚糖衍生物.研究了其对阳离子的吸附性能后发现,与没有稳定构象的杯[6]芳烃接枝壳聚糖衍生物相比,具有稳定杯式构象的杯[6]芳烃壳聚糖对离子的选择性吸附性能大为提高,尤其是对Na+和Ag+表现出较好的选择性吸附能力.
<Abstrcat>By reacting tetra-epoxy-propyl calix[6]-1,4-crown-4 with chitosan, a new type Chitosan derivative grafted by tetra-epoxy-propyl calix[6]-1,4-crown-4 were synthesized. It is found that its adsorption selectivity are higher than that of chitosan grafted by calix[6]arene with no stable conformation. It shows good selective adsorption capability towards Na^+ and Ag^+ among the tested cations.
