文摘 铯是核事故放射性粉尘中主要危害的核元素之一,建立对铯等核素的快速有效的检测监测是核事故应急的重要研究方向。建立了一种基于共线双脉冲激光诱导击穿光谱(DP-LIBS)技术的核素铯检测方法。对采集延时优化实验发现采集延时为2.0 ms,光谱信号最强。两激光脉冲间隔时间为3.8 ms时,信号最好。通过对叶片样品压片进行定量分析,采用CsI: 894.3 nm为分析线,拟合曲线的拟合系数R~2为0.91。进一步利用DP-LIBS对不同浓度Cscl处理的红叶石楠叶片进行直接分析,结果显示:不同浓度Cscl处理的叶片在CsI: 894.3 nm处有明显发射谱线的,建立定标曲线的拟合系数为0.73;证明LIBS技术可以实现对环境样品核素铯含量的快速检测的可行性。
其他语种文摘 In nuclear accident radioactive dust, Cesium is one of the main nuclear. So establishing fast and effective detection of the cesium and other elements is an important research direction of nuclear accident emergency. This study establishes a collinear double pulses laser induced breakdown spectroscopy (DP-LIBS) technology of nuclide cesium detection method. Optimization experiment of gate delay time finds that the signal spectrum reach maximum enhancement, when the gate delay time is 2.0 ms. When the delay time between two lasers is 3.8 ms, the signal spectrum is best. Through the quantitative analysis of the leaf sample tablet, when the analysis line is CsI: 894.3 nm, fitting coefficient R~2 of fitting curve is 0.91. Further using DP-LIBS to analysis Photiniaxfraseri leaf which is dealt with different concentrations of Cscl, and the result shows that: leaf which is dealt with different concentrations of Cscl has obvious spectrum in CsI: 894.3 nm, fitting coefficient of fitting curve is 0.73. The feasibility are proved that LIBS technology can achieve rapid detection of radionuclide cesium content in environment.
