The concentration of uranium in seawater is remarkably constant at 3.3 mg U/m3. The main uranium species in seawater is the stable anionic tricarbonate-uranyl complex, UO,(CO,):- (Saito and Miyauchi, 1981, 1982). Marine uranium displays no detectable deviation from the norrnal terrestrial U-235/U-23
A number of lightly cross-linked poly (acrylonitrile-co-divinylbenzene) beads ( RN-5 ) have been synthesized by suspension polymerization. The use of solvating diluents such as chloroform, dichloroethane, and tetrachloroethane resulted in copolymer beads having highly porous structures. The chelatin
