| Outline of Final Research Achievements |
Although the molecular mixing state in a small space is important in many applications, it has not understood yet by the experimental difficulties. In this research, we developed new facilities for precise determination of rate of adsorption, and adsorption isotherm of each component in mixing adsorption, by using pressure feedback system. We applied this measurement system and determined the rate of adsorption of the activated carbon-water, mesoporous silica-nitrogen, and etc. systems. Furthermore, for the activated carbon-water-ethanol mixing system, we applied the component adsorption isotherm measurement and also X-ray, neutron diffraction measurements, and reverse Monte-Carlo analysis for determination of molecular mixing-state in the nanospaces.
The results of these experiment are variable information for the understanding and efficiency applying for the using of porous materials for molecular separation and storages.
