Abstract  

Two radiochemical separation methods were developed for the separation of 88Y from a SrS target (3.2 g, pressed into a 19 mm disc) and Al (2.5 g, the capsule contained the target). The first method was based on solvent extraction technique using undiluted TBP/HNO3 system and the second was an extraction chromatography using a column packed with TBP-impregnated Amberlite XAD-4 resin. A simple procedure was used for the impregnation of the XAD-4 resin with TBP. For both methods concentrated nitric acid was used for extraction/adsorption and 2M HCl for back extraction/elution of 88Y. In terms of recovery of 88Y, the solvent (TBP)-impregnated resin showed better results (average 91.2% compared to 88.9% with extraction).
