Analytical Chemistry with Ice as Functional Material

以冰和掺盐冰为功能材料，发展了各种分析方法，包括层析、微反应器等。例如，我们可以使用掺盐冰作为微反应器来检测直径为1米的液体包裹体中的1000个镁离子。这有力地表明，用掺盐的冰作为微量反应的平台，可以进行灵敏的分析。这些分析研究表明，在与冰共存的液体中，某些反应非常容易进行。此外，X射线吸收精细结构分析还揭示了体相掺杂冰与其表面离子水化结构的差异。

Various analytical methods, including chromatography, microreactor etc, have been developed with ice and salt-doped ice as functional materials. We can, for example, detect 1000 magnesium ions confined in a liquid inclusion with a diameter of 1. m using salt-doped ice as a microreactor. This strongly suggests that sensitive analyses are possible with salt-doped ice as a platform for microreaction. These analytical studies have revealed that some reactions are remarkably facilitated in a liquid phase coexistent with ice. In addition, X-ray absorption fine structural analyses have revealed the difference in the hydration structure of ions between in bulk doped ice and on its surface.
