EFFECT OF SINGLE-WALLED CARBON NANOTUBES ON HYDROXYPROPYL-β-CYCLODEXTRIN STATIONARY PHASE
In the present work, we describe a novel application of functionalized single-walled carbon nanotubes (SWCNTs) as a stationary phase for the liquid chromatographic separation of polycyclic aromatic hydrocarbons and structurally similar analogues. The SWCNTs were first oxidized to give carboxylic der...
