Effect of amino acid on the adsorption behavior of radiozinc in seawater.
Effect of dissolved amino acid on the adsorption behavior of radiozinc to cation exchange resin and montmorillonite was studied in the artificial seawater. The adsorption of radiozinc showed a tendency to decrease in the order of magnitude of the stability constant of zinc-amino acid complex. On the other hand, the adsorption of radiozinc in the presence of alanine on the montmorillonite was increased, presumably because the methyl group which was independent of the coordination of alanine with Zn2+ ion had maintained the interaction with the surface hydroxyl group of montmorillonite.
