Beschreibungen/Notizen

• A novel amidoxime‐group‐containing adsorbent of hollow‐fiber form (AO‐H fiber) was prepared by radiation‐induced graft polymerization of acrylonitrile onto a polyethylene hollow fiber, followed by chemical conversion of the produced cyano group to an amidoxime group. Distribution of the amidoxime group was uniform throughout the hollow‐fiber membrane. The fixed‐bed adsorption column, 30 cm in length and charged with the bundle of AO‐H fibers, was found to adsorb uranium from natural seawater at a sufficiently high rate: 0.66 mg uranium per g of adsorbent in 25 days.
