MIXED BED ION EXCHANGE FOR THE REMOVAL OF RADIOACTIVITY
Experimental work using mixed bed ion-exchange resins for removing old mixed fission products from tap water showed that the highest decontamination factors were obtained when the water was adjusted to pH 2.5 with nitric acid. This adjustment increased the anion content of the water and it is therefore recommended that a 3:1 ratio of anion to cation resin be used. Flow rate appears to be an important consideration in removing radioactivity and should not exceed 2 gpm per cubic foot of mixed resin. The capacity of a mixed bed exchanger for the removal of radioactivity is based on the amount of total dissolved solids in the feed. The lower the dissolved solids content the larger the throughput.
