摘要

使用滤纸作为样品基底，探索了激光诱导击穿光谱法来估算金属燃料和热化学后处理流中的锆含量。确定了 339.20 纳米波长的 Zr（II）发射线，并将其用于定量测定。将 Zr 的强度归一化为 C/Y 发射线作为内标，得到校准曲线，以获得更好的线性。通过比较模拟样品中的测量值与 ICP-OES 的测量值，测试了 LIBS 估算锆的分析能力。测量值之间的良好一致性证实了 LIBS 在核气流中的应用能力。

Feasibility of laser induced breakdown spectroscopy for quantification of zirconium in nuclear streams

Laser induced breakdown spectroscopy is explored for the estimation of Zr in metallic fuel and pyrochemical reprocessing stream using filter paper as a sample substrate. Zr(II) emission line at 339.20 nm has been identified and used for its quantitative determination. Calibration curves are obtained after normalizing the intensity of Zr to C/Y emission lines as an internal standard, to get better linearity. Analytical capability of LIBS for Zr estimation is tested by comparing the measured value with ICP-OES in simulated samples. Good agreement between the measured values confirms the ability of LIBS application in nuclear streams.
