Peimli] Solid-liquid extraction behaviour of Cs and Na has been investigated, using 12-crown-4, 15-crown-5, 18-crown-6, dibenzo-18-crown-6, diamino-dibenzo-18-crown-6 and dinitro-dibenzo-18-crown-6 on Chromosorb, as neutral macrocyclic ligands and trichloroacetate in aqueous phase as an anionic counter ion of high dielectric constant. The dynamic extraction behaviour of Cs and Na was studied in an extraction chromatographic column by using different crown ethers loaded on a solid support. In some cases high separation factors were observed. Surface effects were found to disturb the extraction equilibrium. In the case of Cs the results did not follow the expected trend observed so far with other extraction systems.
