Chromatography of Some Metal Ions on Silica Gel Thin Layers in Butanol-Formic Acid Media

摘要

Chromato graphic behaviour of some metal ions on silica gel thin layers has been studied in butanol#x2014;formic acid media. The results have been compared with those obtained in aqueous formic acid medium. Many important and analytically difficult separations have been achieved. Some thin layer chromato graphic parameters for the separation of Vo2+from numerous metal ions using 20.0 M formic acid in butanol have been determined.
