Development of ultrafiltration and adsorbents: October 1980-March 1981
Reverse osmosis, on a pilot-plant scale, was successful in removing large percentages of cesium-137 from aqueous streams. The relative effectiveness of three membrane types, 0, 50, and 97% salt rejection, in cesium removal was explored. The 97% salt rejection membrane was the most effective, generally removing 97% of the cesium. An interaction design experimental series was performed to determine the extent of interference, from factors found previously, on the removal of cesium-137 by four ion exchange resins. The interfering factors used were ionic sodium, potassium, and calcium. These factors were found to have no effect on cesium removal by the resins at the ionic concentrations that are amenable to resin treatment. The removal of cesium-137 from a solution containing a large amount of sodium hydroxide was laboratory tested. The best process, under the existing conditions, was found to be chemical precipitation. The precipitation could be accomplished by sodium tetraphenyl boron or copper ferrocyanide.
