| Outline of Final Research Achievements |
[Design of environmental purification materials using fibers] I found that various fibers adsorb organic compounds selectively by each fiber when they are put in the organic compounds vapor mixture atmosphere. A serious of poly(amino acid)s were prepared in order to consider the adsorption property of protein fibers. When the poly(amino acid)s were put in organic compound vapor mixture atmosphere, each poly(amino acid) showed each own selective adsorption pattern. As a result, for example, it was found that poly(L-alanine) and poly(L-valine) can be distinguished from each other by the present adsorption method, although an IR spectroscopy is not effective for it. [Handling of radioactive cesium-adsorbed dust] Radioactive cesium was chemically tested and it was found that it exists in a "water-insoluble state". Assuming that the radioactive cesium adsorbed dust has a negative charge, the adsorption by fibers having a positive charge was examined. The results are under consideration.
