EXPERIMENT 19 (Contd. )
Variations in cesium and strontium decontamination factors are a result
of varying the pH of the feed. Greater cesium removal was observed
when the pH was near neutral, but the greatest strontium removal was
observed when the pH was low (2. 5). The optimum pH for removing
these two isotopes is between 3. 5 and 4.5.

EXPERIMENT 21OBJECTIVES
CONDITIONS
FeedTo study the operation of the steam stripper and
measure the efficiency with which ammonia is steam
stripped at varying feed flow rates.
Purex tank farm condensateAdsorbents None
RESULTS AND CONCLUSIONS
Holding all other system parameters constant, the feed rate to the
steam stripper was varied from 60 ml/min to 90 ml/min resulting in
a change of overhead flow rate from 12 ml/min to 6 ml/min. The
ammonia in the steam stripper bottom stream remained fairly constant
at 2.3 mg/liter.
