Description
Summary:R F values for 52 metals obtained on DEAE-cellulose in binary solvent systems were surveyed to evaluate the use of DEAE-cellulose in inorganic thin-layer chromatography. R F values were measured as a function of hydrochloric acid concentration in binary solvent systems consisting of hydrochloric acid and an organic solvent (1:20) such as methanol, n-butanol, acetone, tetrahydrofuran, acetic acid and cyclohexanone. Useful multicomponent separations are presented to demonstrate the use of R F measurements for predicting separations in these solvent systems. All the solvent systems tested also afford separations of particular metals when the organic solvent and hydrochloric acid concentrations are specifically selected; thus, As (III) and Ge can be separated from fifty metals specifically as well as from each other. Ion-exchange and partition distribution were proposed as the mechanisms controlling the metal behavior on DEAE-cellulose for the methanolic acid system and for the other five solvent systems, respectively.
