内容記述Zeolites combined with insoluble metal ferrocyanides are known as adsorbents capable of specifically capturing cesium ions and attract much attention, due to its easy operation at sites for processing water contaminated with radioisotopes. To achieve more effective adsorption, we prepared a novel M-FC-impregnated fiber by radiation-induced graft polymerization and subsequent chemical modifications. Cobalt ions were bound to a sodium styrene sulfonate-grafted 6-nylon fiber via an ion-exchange interaction. Subsequently, the bound cobalt ions were reacted with potassium ferrocyanide to form insoluble or sparingly soluble cobalt-ferrocyanide (Co-FC). The resultant Co-FC-impregnated fiber with a Co-FC content of 7.3% exhibited a high affinity to cesium ions in the presence of NaCl. Such fibers can be fabricated into various fiber modules suitable for the removal of radioisotopes at sites.
