Outline of Final Research Achievements

A composite of hydroxyapatite and natural zeolite treated individually with Cu(II) and aminopropyltriethoxysilane (APES) was confirmed to capture ammonia, hydrogen sulfide, and acetaldehyde immediately. In addition, the APES treatment enhanced adsorption ability for nonenal gas known as a component of body odor of old people. The adsorption ability for each odor was assumed to be affected not only by the content of modification agent but also by the variety and the state of existence of the agent. It is necessary to design a porous block with which odors can interact effectively as well as its inside in the future.
