This study investigates the dissolution behavior of oxide layers containing radionuclides using perfluorocarbon (PFC) emulsion as a reusable medium. Chemicals such as PFC, anionic surfactant, and HSO are used for preparing the PFC emulsion, and emulsified using an ultrasonication process. The FTIR results show O-H stretching that is formed by the interaction of the carboxyl group of the anionic surfactant with the hydroxyl group of water containing HSO, and find that the HSO can be homogeneously dispersed in the PFC-anionic surfactant-HSO emulsion. The dissolution test of the simulated CrO specimen is conducted using PFC emulsion containing KMnO. Through the weight losses of specimens and Scanning Electron Microscope-Energy Dispersive X-ray Spectrometer (SEM-EDS) analysis, it is confirmed that the CrO layer on the SUS304 specimen is easily dissolved using PFC emulsion. During the dissolution of the CrO, it is observed that the dispersed HSO-KMnO became unstable and separated from PFC emulsion. Based on these results, the behavior of the PFC emulsion during the dissolution of the oxide layer is explained.
本研究使用全氟碳（PFC）乳液作为可重复使用的介质，研究了含放射性核素的氧化物层的溶解行为。PFC、阴离子表面活性剂和 HSO 等化学品用于制备 PFC 乳液，并通过超声处理进行乳化。FTIR 结果表明，O-H 伸缩是由阴离子表面活性剂的羧基与含有 HSO 的水的羟基相互作用形成的，并且发现 HSO 可以均匀地分散在 PFC-阴离子表面活性剂-HSO 乳液中。使用含有 KMnO 的 PFC 乳液对模拟的 CrO 样品进行溶解试验。通过样品的重量损失和扫描电子显微镜-能量色散 X 射线光谱仪（SEM-EDS）分析，证实了 PFC 乳液容易溶解 SUS304 样品上的 CrO 层。在 CrO 的溶解过程中，观察到分散的 HSO-KMnO 变得不稳定并从 PFC 乳液中分离出来。基于这些结果，解释了 PFC 乳液在氧化物层溶解过程中的行为。
