Abstract
The adsorption behaviour of 46 metals on layers of DEAE-cellulose has been examined in aqueous oxalic acid media. R F values are given as a function of oxalic acid concentration over the range 0.010–0.30 M and are compared with those obtained in a similar manner with Avicel SF. R F data are also presented for 48 metals in oxalic acid-hydrochloric acid mixtures, where the oxalic acid concentration was kept constant at either 0.030 or 0.25 M and that of hydrochloric acid was varied from 0.010 to 3.0 M. Pronounced ion exchange takes place in oxalic acid media for many metals, but a limited number of metals are adsorbed on DEAE-cellulose from the mixed acid media. The versatility of the chromatographic system investigated is demonstrated by many multi-component separations conducted without marked tailing.
