Abstract Carbon nanotube (CNT), a well-known carbon-based nanomaterial has drawn much attention in many application fields including chemistry in the last few decades. Many researchers and scientists have shown huge interest to improve the extraction methodologies and adopt their applications in combination with chromatography technique. With respect to this, the exceptional applications of CNTs have been introduced as extraction sorbent due to their excellent inborn physical and chemical properties. In particular, CNTs have consistently been used as adsorbents in various techniques including solid-phase micro-extraction, solid-phase extraction, micro dispersive slid phase extraction, magnetic dispersive solid phase extraction, analytes enrichment, sample fractionation and clean-up as well as support for many derivatization reactions. Many research papers have discussed the successful use of CNTs to overcome the limitations of the extraction techniques due to their excellent sorbent capacity. In addition, considering the clear need to make chromatographic technique more successful, the applications of CNTs have been reported in the literatures in details as stationary and pseudo-stationary phases for the separation and extraction of challenging compounds. Because of the higher thermal and chemical stability, CNTs have been anticipated as stationary phase modifier for chromatographic applications to avoid bleeding of the columns and enable the analysis even at very high temperature (1200 °C). In liquid chromatography CNTs have primarily been used in combination with other packing materials (silica) and sometimes incorporated in a porous polymeric monolith. Therefore, the recent utilizations of CNTs as extraction materials and stationary phases have been illustrated in the current review and a table listing the details applications of CNTs in aforementioned field is provided as well. We believe that the review will help researcher to gain vast knowledge about application of carbon nanotubes in the field of separation chemistry.

碳纳米管在萃取和色谱分析中的应用:综述

摘要 碳纳米管(CNT)是一种众所周知的碳基纳米材料,在过去的几十年里,在包括化学在内的许多应用领域引起了广泛关注。许多研究人员和科学家对改进提取方法并将其应用与色谱技术结合起来表现出极大的兴趣。就此而言,碳纳米管因其优异的物理和化学性质而被引入作为提取吸附剂的特殊应用。特别是,碳纳米管一直被用作各种技术中的吸附剂,包括固相微萃取、固相萃取、微分散滑相萃取、磁分散固相萃取、分析物富集、样品分离和净化以及支持许多衍生反应。许多研究论文讨论了成功使用 CNT 来克服提取技术的局限性,因为它们具有出色的吸附能力。此外,考虑到明显需要使色谱技术更加成功,文献中详细报道了 CNT 作为固定相和拟固定相用于分离和提取具有挑战性的化合物的应用。由于具有更高的热稳定性和化学稳定性,因此人们期望将 CNT 用作色谱应用的固定相改性剂,以避免色谱柱流失,即使在非常高的温度 (1200 °C) 下也能进行分析。在液相色谱中,碳纳米管主要与其他填充材料(二氧化硅)结合使用,有时并入多孔聚合物整料中。所以,最近的 CNTs 作为萃取材料和固定相的应用已经在当前的综述中进行了说明,并提供了一个表格,列出了 CNTs 在上述领域的详细应用。我们相信该综述将有助于研究人员获得有关碳纳米管在分离化学领域应用的广泛知识。
