UN PROCEDIMIENTO PARA LA SEPARACION DE UN ISOTOPO DE GADOLINIO SELECCCIONADO ENTRE GD 155,GD 156 O GD 157,SOLO O MEZCLADO CON LOS OTROS, DE UNA MEZCLA DE ISOTOPOS DE GADOLINIO QUE LAS CONTIENE.

摘要

An efficient and economical separation of the gadolinium isotopes Gd155, Gd156 and/or Gd157 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.
