Abstract
Alpha particle bombardment on thick silver target produced no-carrier-added (NCA) 111In and 109Cd radioisotopes in the matrix. NCA 111In and 109Cd were separated from the target matrix by solid–liquid extraction using glass wool surface. At 10−2 M HNO3 concentration, ~100 % 111In and 93 % 109Cd were adsorbed on the glass wool surface along with 16 % contamination of bulk Ag. After quantitative removal of bulk Ag from glass wool surface by de-ionized water, 111In and 109Cd were desorbed by 0.1 M HNO3. The mutual separation between 111In and 109Cd was achieved by column chromatography using Dowex 50WX-50 resin.
