| Abstract: | The separation of two alkaline amino acids(arginine and lysine) was performed using 1-butyl-3-methylimidazolium tetrafluoroborate ionic liquid(BF4) as the eluent additives in thin layer chromatography.The addition of ionic liquid improved the separation the free silanol group markedly.The retardation factor(Rf) of the analytes firstly increased and then remained constant with the increase of the concentration of ionic liquids.In addition,the comparison results showed that the inhibition effect of PF6 for fr... |
