Radiation stability of sodium titanate ion exchange materials

PDF Version Also Available for Download.

Description

Sodium titanate and sodium titanate loaded macroreticular resin are being considered as ion exchangers to remove /sup 90/Sr and actinides from the large volume of defense waste stored at Hanford Site in Washington. Preliminary studies to determine the radiation effect on Sr/sup +2/ and I/sup -/ capacity of these ion-exchange materials were conducted. Samples of sodium titanate powder, sodium titanate loaded macroreticular resin, as well as the nitrate form of macroreticular anion resin were irradiated with up to 2 x 10/sup 9/ Rads of /sup 60/Co gamma rays. Sodium titanate cation capacity decreased about 50% while the sodium titanate loaded ... continued below

Description

Sodium titanate and sodium titanate loaded macroreticular resin are being considered as ion exchangers to remove /sup 90/Sr and actinides from the large volume of defense waste stored at Hanford Site in Washington. Preliminary studies to determine the radiation effect on Sr/sup +2/ and I/sup -/ capacity of these ion-exchange materials were conducted. Samples of sodium titanate powder, sodium titanate loaded macroreticular resin, as well as the nitrate form of macroreticular anion resin were irradiated with up to 2 x 10/sup 9/ Rads of /sup 60/Co gamma rays. Sodium titanate cation capacity decreased about 50% while the sodium titanate loaded macroeticular resin displayed a dramatic decrease in cation capacity when irradiated with 10/sup 8/-10/sup 9/ Rad. The latter decrease is tentatively ascribed to radiation damage to the organic portion which subsequently inhibits interaction with the contained sodium titanate. The anion capacity of both macroreticular resin and sodium titanate loaded macroreticular resin exhibited significant decreases with increasing radiation exposure. These results suggest that consideration should be given to the potential effects of radiation degradation if column regeneration is to be used. 5 figures, 2 tables.
