• The effect of physicochemical properties of two-phase liquid systems (interfacial tension and differences in the densities and viscosities of the two phases) on the retention of the stationary phase in a rotating coil column was studied, taking as examples complex liquid systems containing an organic solvent (n-decane, n-hexane, chloroform, carbon tetrachloride and methylisobutylketone), an extracting reagent (di-2-ethylhexylphosphoric acid, tri-n-butyl phosphate, trioctyl amine), water, and a mineral salt (ammonium sulfate). Extracting reagent additions to the organic solvent and salt additions in the aqueous phase lead to changes in physicochemical properties of the liquid system and affect, strongly, the stationary organic phase retention. The influence of the rotational speed on the stationary phase retention for different systems was also investigated. Some recommendations for the selection of proper systems for CCC separations are formulated.
