为在线监测聚醚醚酮(PEEK)容器内铀(Ⅵ)浓度的可行性,对拉曼光谱法进行了实验验证。结果表明,容器的PEEK材料会影响铀(Ⅵ)的拉曼光谱,使得光谱背景增高,峰强度降低。PEEK材料及PEEK辐照会影响铀(Ⅵ)拉曼信号的稳定性。实验中拉曼探头受到射线辐照,探头及光纤中的石英材料发生变性,从而很大程度上影响了铀(Ⅵ)的拉曼信号。为了解决上述问题,得到准 To verify the feasibility of on-line monitoring of uranium (Ⅵ) concentration in polyetheretherketone (PEEK) containers, Raman spectroscopy was used to verify the feasibility. The results show that the PEEK material in the container will affect the Raman spectrum of uranium (Ⅵ), resulting in an increase of the spectral background and a decrease of the peak intensity. PEEK material and PEEK irradiation will affect the stability of Raman signal of uranium (Ⅵ). In the experiment, the Raman probe was irradiated by radiation, and the quartz material in the probe and the fiber was denatured, which affected the Raman signal of uranium (Ⅵ) to a great extent. In order to solve the above problems, get the prospective
