A Reversed-Phase Thin Layer Chromatographic Separation Of The Light Rare-Earths With A Spectrophotometric Determination
In this study, two, three, four, five, and six rare earths were separated by reversed-phase thin layer chromatography. Selected sample spots were removed from the plate and determined by emission spectroscopy. Di-(2-ethylhexyl)phosphoric acid was used as the stationary phase. This roganic substitute...

| Summary: | In this study, two, three, four, five, and six rare earths were separated by reversed-phase thin layer chromatography. Selected sample spots were removed from the plate and determined by emission spectroscopy.
Di-(2-ethylhexyl)phosphoric acid was used as the stationary phase. This roganic substituted inorganic acid is retained on the adsorbent through hydrogen bonding and is essentially hydrophobic, so that the aqueous mobile phase can pass over it without serious interaction between the two acids. |
