Abstract
The chromatographic behavior of 14 metal ions with aqueous-organic wash liquids on ion-exchange papers is compared with results in columns and thin layers of the same resin. It is shown that many column separations can be obtained on paper, and that paper chromatography can often be used to preevaluate systems for separations on columns. The mechanism for the chromatographic processes and differences between techniques employed with columns and papers are discussed.
