Title:
METHOD FOR SEPARATING RADIOACTIVE COPPER USING CHELATE EXCHANGE RESIN
Document Type and Number:
WIPO Patent Application WO/2010/001728
Kind Code:
A1
Abstract:
Provided is a method for quickly separating radioactive copper from nickel containing radioactive copper and radioactive cobalt. The nickel that contains radioactive copper and radioactive cobalt is dissolved in an acidic solution and passed through a chelate exchange resin-filled column to retain the nickel, the radioactive copper, and the radioactive cobalt in the chelate exchange resin. Then the radioactive copper and the radioactive cobalt are eluted by passing an acidic solution through the chelate exchange resin-filled column. Then an acidic solution that is more highly concentrated than the previous acidic solution is passed through the chelate exchange resin-filled column after the nickel and radioactive cobalt elution in order to elute the radioactive copper.
