| Popis: | Yttrium-88 was produced from irradiation of a SrCl2 target (4.8 g, pressed into a 19 mm disc) by 33 MeV proton beam at a current of up to 90 mA. Chelating resin Chelex 100 (H+ form, 100-200 mesh) was used for the separation of yttrium radionuclides (including 88Y) from strontium. 0.01M nitric acid was used for the dissolution of target (100 ml), retention of Y and elution of Sr (200 ml). For the elution of yttrium, 25 ml 1M HNO3 was employed. The column was 4 cm long with internal diameter of 1.6 cm. The flow rate was 1 ml/min throughout the separation procedure. The 88Y recovery yield was 94% average and the stable Sr content in the final product (5 ml 0.1M HCl) was estimated to be less than 3 ppm. |
