Effects Of Ph

Effects of pH in the range of 5 to 8 and uranium concentration in the range of 0.02 mg/l to 25 mg/l on the removal of uranium with a strong base anion exchange resin (SBA) and a chelating aminophosphonate resin were studied. The results of the batch and column mode experiments clearly showed that the aminophosphonate resin was an efficient exchanger for the removal of uranium at pH values close to 5 and the SBA resin at higher pH values. In the column experiments, where altogether 2000 bed volumes of drinking water simulant were processed with these exchangers, the uptake of uranium was as high as 99.8% by the aminophosphonate resin at pH 5 and 99.7% by the SBA resin at pH 8.

The results of studies of the sorption of EDTA complexes with ions Co(II) and Fe(III) on anion exchange resin AB-17-8 used in mixed filters of special water treatment apparatus of NPP are presented. The character of the sorption process of complexes Co(II)-EDTA and Fe(III)-EDTA in acidic media depending on the pH and salt background of solutions simulating deactivating solutions formed after the dissolution of iron oxide compounds containing cobalt radionuclides was studied. It has been shown that upon deactivation of spent ion-exchanged resins with acid solutions of EDTA salts, the secondary sorption of EDTA complexes with cobalt radionuclides on anion exchange resin can be reduced by lowering the pH of the deactivating solutions and increasing the concentration of competing inorganic anions, with no noticeable competing effects of the complexes Fe(III)-EDTA.
