Abstract
A method for separating of at least two transition metals, the method comprising: injecting a feed solution into a chromatography column comprising a chromatographic support media, the feed solution comprising at least two transition metals; eluting the feed from the column in an elution cycle by flowing an eluent through the column, wherein a concentration of the eluent is reduced during the elution cycle prior to elution of at least one of the transition metals.
Claims12
A method for separating at least two transition metals from each other, the method comprising:
- injecting a feed solution into a chromatography column comprising a chromatographic support media, the feed solution comprising at least two transition metals;
- eluting the feed from the column in an elution cycle by flowing an eluent through the column,
- wherein a concentration of the eluent is reduced during the elution cycle prior to elution of at least one of the transition metals, and
- wherein the eluent is HCl.
