Development of a simple procedure for the analysis of Pu, Am, Cm and Sr in low-level liquid radioactive effluents

摘要

A new sequential procedure for the analysis of Pu, Am, Cm and Sr in low-level liquid radioactive effluents is presented. The proposed method utilises an actinide specific extraction chromatographic resin (TRU-Resin) for the isolation and separation of the actinides. ~(90)Sr determination is accomplished via analysis of its progeny ~(90)Y, which is purified with TBP extraction. The proposed method is simpler and faster than traditional ion exchange, extraction and precipitation methods used in routine analysis of actinides and ~(90)Sr. The chemical yield of all analytes, when analysing 200 ml low-level effluent, is between 80-95%.
