APPLICATIONS OF CARBON NANNOTUBES IN CHROMATOGRAPHY

Abstract: Carbon nanotubes (CNTs) are cylindrical allotropes of carbon. They were discovered in the year 1991 and they have a unique structure. Due to the huge production and applications of carbon nanotubes, they have attracted many industries and companies towards themselves as they are used in nanotechnology, membranes, capacitors, polymers, metallic surfaces, ceramics, nanomedicine etc. The main motive of this paper is to highlight the basic adsorption capacity of the Carbon nanotubes, and it also reveals that the thermal and chemical stability make them suitable materials as new stationary phases and pseudostationary phases. And also for adsorbents in solid-phase extraction (SPE) and solid-phase microextraction (SPME). This article describes the latest applications of Carbon nanotubes (CNTs) in chromatography.
