CHROMATOGTRAPHY APPARATUS AND ELECTROLYTIC METHOD FOR PURIFYING AN AQUEOUS STREAM CONTAINING A CONTAMINANT IOM

摘要

An electrolytic method and apparatus is provided for purifying an aqueous stream, including at least one contaminant ion. In one embodiment, the eluent stream flows through a purifying flow channel, including ion exchange bed, an electric field is applied through the flowing eluent stream in the purifying flow channel, and the contaminant ion is removed from the eluent stream. In another embodiment, no electric field is applied and the ion exchange bed is periodically regenerated. Two beds may be used with one bed on line while the other bed is regenerated followed by a reversal of flow.
