Abstract: The different characteristics of saturated solutions of Xe and Xe existing as ultra-fine bubble water (Xe-UFB) were observed using X-ray absorption fine structure (XAFS) analysis. The dissolved concentration of the 2 atm Xe-saturated solution was measured accurately by changing the XAFS measurement spectrum. For Xe-UFB, the time change of the dissolved Xe concentration at the time of exposure to the atmosphere was obtained. Additionally, the calculation was obtained for the saturated solution. Based on the storage condition of Xe-UFB, it was found that the concentration of Xe in the aqueous solution before exposure to the atmosphere differed after 1 day compared to its half-life, even in a closed refrigerated storage condition. Xe-UFB tends to increase immediately after generation but tends to decrease after one day, based on the mode particle size of bubble concentration and change in concentration.

纯水中氙气超细气泡的XAFS分析

摘要：利用X射线吸收精细结构（XAFS）分析，观察了Xe饱和溶液和以超细气泡水（Xe-UFB）形式存在的Xe饱和溶液的不同特性。通过改变 XAFS 测量光谱，准确测量了 2 个大气压 Xe 饱和溶液的溶解浓度。对于 Xe-UFB，获得暴露于大气时溶解的 Xe 浓度随时间的变化。此外，计算是针对饱和溶液获得的。根据 Xe-UFB 的储存条件，发现暴露于大气前的水溶液中的 Xe 浓度在 1 天后与其半衰期相比有所不同，即使在密闭冷藏条件下也是如此。Xe-UFB 趋向于在生成后立即增加，但在一天后趋于减少，
