SEPARATION OF GADOLINIUM ISOTOPE

摘要

An efficient and economical separation of the gadolinium isotopes Gd<1><5><5>, Gd<1><5><6> or Gd<1><5><7> from mixtures containing the same is effected by a liquid chromatographic column system using an ion exchange resin and an eluant solution. A portion of the eluant solution is used to saturate the columns and a feed solution containing the mixture of gadolinium isotopes is charged to the columns. Further eluant solution is passed through the saturated columns containing the feed solution to form a fraction of eluant solution rich in the desired gadolinium isotopes which is separated from the remainder of the eluant upon discharge from the columns.
