| 中文摘要 |
| 将3′-端烯丙基苯并15-冠-5和4′-端烯丙基苯并15-冠-5接枝到壳聚糖或交联壳聚糖上,合成了4种新型的壳聚糖冠醚。并研究了这4种壳聚糖冠醚对Pd2+、Cu2+、Hg2+的静态吸附性能。结果表明,这4种吸附剂对Pd2+具有良好的吸附性能,并能在Cu2+和Hg2+共存的条件下选择吸附Pd2+。 |
| 英文摘要 |
| Four novel chitosancrown ethers(3X-CTS,4X-CTS,3X-CCTS and 4X-CCTS)were synthesized by the reaction of 3'-propenyl benzo 15-crown-5 and 4'-propenyl benzo 15-crown-5 with chitosan or crosslinked chitosan.The static adsorption properties of them for metal ions(Pd2+,Cu2+and Hg2+)were studied.The results showed the adsorbents had good adsorption characterization and good adsorption selectivity for Pd2+ when Cu2+ and Hg2+ were in coexistence. |
