Popis: Enrichment of lithium isotopes by displacement chromatography on strong acid cation exchanger was investigated. Narrow particle fraction of Dowex 50 WX 2 cation exchanger having diameter of 150–200 µm and total exchange capacity of 1.31 meq mL−1 was used as stationary phase. As a mobile phase, 1 mol L−1 solution of ammonium nitrate solution was used. Shape and position of Li chromatographic peak, was determined by atomic emission spectroscopy (AES). Isotope ratio was estimated by ICP–MS after 1, 8 and 10 enrichment steps. Value of separation factor for 6Li in one step was determined to be 1.027.
