摘要
A method is described for separating radioyttrium from strontium within 30-40 min. The yield of radioyttrium amounts to 97% and the strontium impurity occurs at 8.2 ppm level. Radioyttrium (containing (86)Y, (87)Y and (88)Y) was produced by proton-induced nuclear reactions on (nat)SrCO(3) deposited on Cu backing. Irradiated target material was removed with acetone and 8 M HCl solution from copper substrate, followed by ethyl cellulose (EC) litter removal. Optimal radioyttrium separations from Cu and (65)Zn activities were obtained by loading the mixture on Dowex-1 x 8 anion exchange resin and eluting with 8 M HCl, followed by precipitation of (nat)Sr as SrSO(4) while radioyttrium passed through the filter paper.
