Kinetics of uranium adsorption from seawater with imidedioxime adsorbent

Journal Article · · Separation Science and Technology
Complexation between glutar-imidedioxime and uranyl ion in artificial seawater containing 600 ppm uranium at pH 10.3 was investigated by a spectroscopic method. The complexation rate and the complex concentration at equilibrium increased with decreasing concentration of total carbonate ions. In the range of the total carbonate concentration of 4 x 10{sup {minus}3} to 5 x 10{sup {minus}2} mol{center_dot}L{sup {minus}1}, the complexation proceeded by ligand exchange between a carbonate ion and a deprotonated imidedioxime. At lower total carbonate concentrations, the elimination of more than two carbonate ions from one uranyl ion was suggested.
