POSSIBILITY OF SEPARATION OF COPPER AND SILVER ZONES IN AN ALLOY OF COPPER AND SILVER BY ZINC, CHROMATOGRAPHICALLY

It is found that the chromatographic order Cu-Ag-Zn with alumina as adsorbent is reversed in dilute solutions to Cu-Zn-Ag. This is shown to be due to the preferential adsorption of Zn over the Ag in dilute solutions. It is suggested that this method may he used to separate and estimate the Cu-Ag alloys.
