摘要

摘要: 为了采用同位素稀释质谱分析法准确测定环境中的痕量⁹⁹Tc，需要以⁹⁷Tc作稀释剂。采用天然Ru为辐照原料，建立了碱熔→水浸取→沉淀→萃取→阴离子交换的化学分离流程，确定了⁹⁷Tc的制备工艺。该流程的化学产额大于70％，对Ru的去污因子大于10^７。 

Abstract: The most sensitive analytical technique of ⁹⁹Tc is isotope dilution mass spectrometry with ⁹⁷Tc as yield tracer. ⁹⁷Tc was obtained by the irradiation of 2 g natural ruthenium metal. ⁹⁷Tc is isolated from the sample by combined ionexchange chromatography, precipitation and ion-association solvent extraction technique. ⁹⁹Tc^mand ¹⁰³Ru are used as tracers in this method. The chemical recovery of Tc is more than 70% and the decontamination factor is more than 10^７.
