On Separation of Rare-Earth Metals in Cascade of Sieve Tray Extraction Columns in the Liquid–Liquid Chromatography Mode

This article presents the experimental results of extraction chromatography separation in a cascade of sieve tray extraction columns operating in the mode of continuous flow of the disperse mobile phase. The possibility of extraction separation of rare-earth metals in a cascade of sieve tray extraction columns operating in the liquid–liquid chromatography mode is demonstrated.
