Decontamination of a solution from strontium-89 by the foam striction concentration of colloids
The purpose of this investigation was to determine the possibility of removing strontium isotopes from solutions by using the foam striction method for concentrating colloids. A series of experiments was conducted using a nitric acid solution free from /sup 89/Sr carrier (half life 54 days). The relative concentration of /sup 89/Sr in the solutions was determined radiometrically. The fraction of the radiation from /sup 90/Sr and the daughter of /sup 90/Y in the preparation used was 1-3%. Preliminary experiments using a column of varying cross section showed that in the absence of precipitants /sup 89/Sr is not concentrated completely in the gelatin foam. In order to form radiocolloids in nitric acid solution containing /sup 89/Sr phosphate ion was introduced by adding the salts Na/sub 2/HPO/sub 4/ x 12H/sub 2/O or Na/sub 3/PO/sub 4/ x 12H/sub 2/O. It was found that the pH value of the medium is of great importance. A marked concentration takes place only in the alkaline region pH greater than or equal to 8. In the case of pH less than or equal to 6 /sup 89/Sr is not generally observed to be extracted into the gelatin foam.
