Abstract
Despite the low concentration of uranium in seawater (3.3 ppb), a spec ial emphasis has been placed on its recovery. Although the concentrati on is low, it has been estimated that the world's oceans contain about 4 x 10(9) tons of uranium-theoretically an unlimited supply of nuclea r fuel. Adsorption has been considered to be a technically feasible pr ocedure for a uranium recovery process with regard to economic and env ironmental impacts. The present paper restricts its coverage to those applications using chelating polymeric resins containing amidoxime gro ups as the most promising adsorbent.
