초록
A chemical separation procedure was devised for the purpose of quantifying the radioactivityconcentration of the recalcitrant nuclide 113Sn in radioisotope (RI) waste. This was accomplished through theutilisation of anion exchange resin and TRU resin in a chemical separation process, which was subsequentlycomplemented by the deployment of Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) andHigh Purity Germanium (HPGe) instrumentation. The target media are rubber, wiper, plastic, stainless steel, andvinyl. The principal interfering elements (uranium, zinc, americium, bismuth, cadmium, iron, nickel, and caesium)and the target element (Sn) were introduced and subjected to testing. The results demonstrated that all interferingelements were effectively removed, and the target element was successfully recovered. The recovery of Sn in theanion exchange resin step was 89, 95, 97, and 87% for rubber, wiper, plastic, and stainless steel, respectively, and92, 81, 84, and 90% in the TRU resin step, respectively. The combined procedure yielded recoveries of 91, 93, 93,and 94% for plastic, rubber and plastic, rubber and vinyl, and vinyl, respectively. Therefore, it can be concluded thatthe proposed chemical separation procedure is suitable for the analysis of 113Sn, and the proposed procedure for theanalysis of the 113Sn nuclide in RI waste samples in this study is considered valid.
