Application of a Mixture of Oxidized Multi-Walled Carbon Nanotubes and D-(-)-Tartaric Acid-Impregnated Silica Gel as Stationary Phases for Thin-Layer Chromatographic Enantioseparation

Article Preview

Abstract:

The oxidized multi-walled carbon nanotubes were prepared by a nitric acid treatment procedure, which were then used as additive in thin-layer chromatography stationary phases for resolution of ofloxacin, mandelic acid and 2-chloro-mandelic acid enantiomers. In a sharp contrast with pristine multi-walled carbon nanotubes/D-(-)-tartaric acid impregnated thin-layer chromatography plates, oxidized multi-walled carbon nanotubes/D-(-)-tartaric acid impregnated plates presented better enantioseparation effects for ofloxacin enantiomers.
