| Research Abstract |
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.
