The chromatographic behavior of 16 metal ions, including Sr, on thin layers of sodium carboxymethylcellulose and Dowex 50X4(Na/sup +/) was investigated. The eluents used were acetate, gluconate, lactate, and oxalate buffer solutions at constant ionic strength. The influence on the R/sub F/ values of some parameters (the affinity of the ions for the exchanger, the concentration and the type of buffer solution) was determined. Criteria are proposed for the analytical use of these parameters. The stability constants of the complexes with the above ligands and the selectivity coefficients of the ions for the two exchangers were calculated. Finally, the validity of the method for the determination of the stability constants for mono- and bidentate ligands is discussed. (auth)
