Separation of no-carrier-added 111In and 109Cd from α-particle induced Ag target using glass wool surface

Abstract

Alpha particle bombardment on thick silver target produced no-carrier-added (NCA) 111 In and 109 Cd radioisotopes in the matrix. NCA 111 In and 109 Cd were separated from the target matrix by solid-liquid extraction using glass wool surface. At 10 -2 M HNO 3 concentration, *100 % 111 In and 93 % 109 Cd 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, 111 In and 109 Cd were desorbed by 0.1 M HNO 3 . The mutual separation between 111 In and 109 Cd was achieved by column chromatography using Dowex 50WX-50 resin.

Across the energy scale: from eV to GeV

“…Two of our works are noteworthy in this respect. We have separated NCA 111 In and 109 Cd from a-particle induced Ag target exploiting preferential adsorption of bulk silver and NCA product radionuclides on glass wool surface [102]. Similarly, 107,109 Cd was separated from proton induced silver target simply by precipitating bulk Ag as AgCl [103].…”
