Latest Patents

Ueki holds a patent for a "Cloth-like radioactive material adsorbent and its manufacturing method." This renewable adsorbent is designed to selectively and efficiently adsorb cesium, allowing for the reuse of the element by eluting the adsorbed cesium. The manufacturing process involves exposing polyethylene (PE) or polypropylene (PP) based non-woven fabric to electron beams. The treated fabric is then contacted with a monomer solution containing acrylonitrile (AN), dimethyl sulfoxide (DMSO), Tween80 as a surfactant, and ammonium molybdophosphate n-hydrate (AMP) as an inorganic ion exchanger. This innovative approach supports the inorganic ion exchanger directly through a non-ionic graft chain.
