| 摘 要： | 使用单壁碳纳米管(SWNTs)作气相色谱的固定相, 并用静态涂渍法在单壁碳纳米管内壁涂渍浓度不同的SE-30固定液. 为考察固定液浓度不同的几根毛细管柱的柱性能, 对多种物质进行了拆分, 并将该拆分结构与直接涂渍SE-30柱的毛细管柱性能进行对照. 实验结果表明: 键合了SWNTS再涂渍SE-30的毛细管柱较之直接涂渍SE-30的毛细管柱拆分效果有所改进, 但存在一定的拖尾现象. 此外, 前者对气体有较好的拆分效果, 且其效果随SE-30浓度按一定规律变化. 从分离性能来看, 键合了SWNTS再涂渍SE-30的固定相对气体的分离具有较好的效果.

| Abstract: | Single-walled carbon nanotubes(SWNTs) open tube columns were coated by the static method using SE-30 solutions of 0.45%,0.90%,1.35%(m/V).To evaluate performance of those columns,hydrocarbons,ketones,aromatic compounds,mixture of methane-ethylene-acetylene were separated by the columns.The resolution results were compared with those obtained on the SE-30 column and SWNTS column,which showed that the SWNTS+SE-30 column possessed better chromatographic performance. |
