ABSTRACT:
By the displacement chromatographic process comprising passing a solution containing a plurality of metallic elements to be separated through a column packed with activated chelating resin, passing an eluent through the column and collecting successive portions of the resultant eluate, the metallic elements can be separated into individual metallic elements not only in a high state of purity but also in a high state of concentration, with a greatly improved column efficiency.
