| Outline of Final Research Achievements |
This study was carried out to prepare functional materials by the chemical modification of various fibers, which leads to the effective use of waste fibers. Anionic monomer grafted cellulose fibers adsorbed metallic ions and cationic surfactants in water. Nonionic organic compounds in water were trapped by rayon fiber. Subsequently, an aqueous cesium chloride solution was examined to consider the property of radioactive cesium compounds. Grafted fiber adsorbed cesium ions more effective than zeolite. But, the fiber did not adsorb cesium ion in the presence of other metallic ions. Radioactive cesium compounds adsorbed in the soil could not be dissolved easily in water. Thus, the removal of cesium dissolved in water is not practical. It was found that the dusts in our buildings contained about 15,000 Bq/kg of radioactive cesium. Thus, the removal of the dusts was examined by using air cleaners. The chemical modification of nonwoven fabric filters for air cleaners was investigated.
