Abstract

The distribution of species along the band during separation by displacement chromatography is discussed from a theoretical view point, using the concepts of the plate theory. Detailed calculations are presented for the determination of the concentration distribution in the rear and the front regions of the band, for the separation of two species originally present in equal amount and having a separation factor of 2. An experimental procedure is described for verifying the theoretical results. Data obtained for the separation of neodymium and samarium and of praseodymium and neodymium, using EDTA as eluant and copper as retaining ion confirmed the validity of the theoretical treatment.
