| Outline of Final Research Achievements |
A new chromatographic method termed surface-bubble-modulated liquid chromatography, that has a hybrid separation medium incorporated with surface nanobubbles, was developed. Nanobubbles can be fixed at the interface between water and a hydrophobic material by delivering water into a dry column packed with a nanoporous material. The incorporation of a gas phase leads to the formation of the hybrid separation system consisting of the gas phase, hydrophobic moieties, and the water/hydrophobic interface or the interfacial water. One can change the volume of the gas phase by pressure applied to the column, which in turn alters the area of water/hydrophobic interface, while the amount of the hydrophobic moiety remains constant. Therefore this strategy provides a novel technique not only for manipulating the separation selectivity by pressure but also for elucidating the mechanism of accumulation or retention of solute compounds in aqueous solutions by a hydrophobic material.
