| Abstract: | In this paper,a multi-walled carbon nanotubes-contained silica monolith was prepared as the promising candidate for HPLC separations.Characterization of the prepared multi-walled carbon nanotubes-contained silica monolith was performed with scanning electron microscopy and surface area machine.Its chromatographic properties were evaluated by using toluene and phenol as samples while n-hexane as the mobile phase.Permeability and column pressure drop were evaluated for separation,and the possible separation m... |
