Abstract
Attempts were made to separate components of metal ion mixtures on columns of iminodiacetate type chelating resin. Distribution coefficients of metal ions in the presence of sulfosalicylic acid and citric acid were calculated in order to determine the proper pH for the most efficient separations. Separations of metal ion mixtures using citric acid or sulfosalicylic acid . solutions as eluting agents were, for the most part, successful, although incomplete elution was observed in some cases.
