The adsorption capacity for Sr and Y with Polyantimonic Acid (PAA) in 0.1 mol/L nitric acid solution was 16.25 mg/mL and 42.1 μg/g respectively. Sr and Y can't be separated with nitric acid solution of different concentration. More than 72% of Y can be eluted with 100 mL 0.02 mol/L EDTA as elution, but PAA was unstable in EDTA solution. 86.2% of Y can be desorbed with 20 mL 0.12 mol/L DTPA at the temperature is 80°C. The results indicated that PAA may be used for 90Y generator preparation, but system of generator should be rational designed to meet requires of 90Y generator. Source
