摘要:

碳纳米管(CNTs)作为一种新型的功能材料,具有优异的物理、化学和机械性能,已经在分析化学领域得到了广泛的关注和应用。通过填充法或原位化学气相沉积法,可制备CNTs气相色谱固定相;将CNTs沉积在硅胶微球或有机聚合物基质微球表面,可制备填充式CNTs液相色谱固定相;通过包埋共聚法将CNTs嵌入聚合物整体柱内,可制备毛细管CNTs液相色谱整体柱。本文主要综述了近年来CNTs(单壁碳纳米管和多壁碳纳米管)用于色谱固定相制备的研究现状,包括气相色谱及液相色谱,并对该领域今后的发展进行展望。

Abstract:

Carbon nanotubes (CNTs) as a new functional material have attracted the interest of scientists and engineers in analytical chemistry, due to their excellent physical, chemical and mechanical properties. The preparation of gas chromatographic stationary phases with CNTs has been performed by packing method or in situ catalytic chemical vapor deposition. The deposition of CNTs on a chromatographic solid matrix (e. g. silica micro-particles or organic polymer microspheres) was carried out to generate a packing material for high performance liquid chromatography. Capillary monolithic columns for liquid chromatography were also prepared by embedding CNTs in polymer monolithic columns. Columns with CNTs have the unique advantages in the separation of aromatic compounds for the π electron system of CNTs. Herein, the recent applications of CNTs in the preparation of chromatographic stationary phases are reviewed, including gas chromatography and liquid chromatography. The future developments in this field are also prospected.
