Abstract:
1. A manufacturing method of cesium adsorbent comprises; generating radical by electron beam exposure to polyethylene (PE) based non-woven fabrics or polyethylene (PE)/polypropylene (PP) based non-woven fabric; forming a graft polymerization product by contacting said non-woven fabrics to a monomer solution manufactured by mixing acrylonitrile (AN), solvent for AN, surfactant and one selected from a group including stannum molybdophosphate, titanium molybdophosphate and ammonium molybdophosphate n-hydrate (AMP) with a relevant weight ratio; immersing the graft polymerization product in toluene, and washing said non-woven fabric entirely; and drying in a vacuum said graft polymerization product in which said AMP is supported after completing washing with toluene.
