摘要
针对中国原子能科学研究院的低放废水处理过程中99Tc的分析 ,研究建立了甲乙酮萃取 /ICP MS测量99Tc的方法。应用建立的方法首次测量了低放废水处理过程中原水、絮凝水、排放水中99Tc的含量 ,并计算出絮凝工段、蒸发工段对99Tc的净化系数。作为比较 ,还用反康普顿Ge(Li)γ谱仪测量了其它放射性核素和用切连科夫液闪直接计数法测量了90 Sr 90
It is established a procedure which includes MEK extraction Tc from NaOH solution, vaporating MEK with 1 mol/L HNO3, then measuring 99Tc with ICP-MS. Using this procedure the 99Tc of varied samples in the low-level liquid waste treatment is first measured. For comparison, the γ-radionuclides in samples are measured with unti-Compton Ge(Li) γ-spectrometry and 90Sr-90Y with Cerenkov counting.
