| Popis: | Chemically modified acidic alumina T stationary phases have been prepared by organosilylation with the trifunctional organosilicon compounds n -octadecyltrichlorosilane, 3-mercaptopropyltri-methoxysilane, and N -(2-aminoethyl)-3-aminopropyltrimethoxysilane. These chemically modified phases were characterized by elemental analysis, measurement of specific surface area, FTIR spectroscopy, 13 C CP/MAS NMR spectroscopy, mass spectrometry, and thermal analysis. The TLC behavior of unmodified and chemically modified acidic alumina T has been tested by separation and identification of some dyes and benzo[ a ]pyrene derivatives. |
