THE REMOVAL OF RADIOACTIVE MATERIAL FROM WATER BY SERIAL COAGULATION, BY ION EXCHANGE, AND BY CHARCOAL ABSORPTION (SALTY DOG VII)
Methods of removing radioactive materials from water by serial coagulation, by ion exchange, and by charcoal adsorption were examined. Results indicate that all of the Ru-106-Rh-106, Zr-95-Nb-95, and Ce-144-Pr-144 present may be removed by serial coagulation, also over 98% of Ba-140-La-140, and Sr-90-Y- 90 can be removed by this method as well as 87.8% of mixed fission products. The capacity of ion exchange resins such as Amberlite Ir-120 for removing Sr-89 from water is essentially independent of flowrate, column length, temperature, and pH. Granular bone charcoal was tested for radioisotope removal from water. The highest removal was obtained with Ag-110 (89.2%) and Pr-144 (88.8%) while the lowest removal was with Na-24 (38.%). Pretreatment of contaminated water with dimethylglyoxime was found to be beneficial in charcoal removal of radioisotopes. Using this additive more than 98% of the Sr-89, Ba-140, La-140, Zr-95, Nb-95, Ca- 45, Y-91, Ag-110, and Ce-144-Pr-144 present were removed. (J.R.D.)
