Abstract
A tritium substitution method having a process of adding an organic substance including at least one of an organic acid, an organic acid alkali salt, a water-soluble amino acid, an organic acid to which a water-soluble amino acid alkali salt is added, an organic acid alkali salt, a water-soluble amino acid, and a water-soluble amino acid alkali salt, to radioactive substance-contaminated water containing tritium, a tritium substitution process of circulating fine bubbles in the contaminated water in which the organic substance has been added to cause a reaction of substituting hydrogen in the α position of a carboxylic acid group by tritium through an interface of the fine bubbles to produce a tritium-substituted product.
Claims13
A method for substituting tritium in tritium-containing water comprising:
- a process of adding an organic substance having a carboxyl group to tritium-containing water, the organic substance including at least one of an organic acid, an organic acid alkali salt, a water-soluble amino acid, an organic acid to which a water-soluble amino acid alkali salt is added, an organic acid alkali salt, a water-soluble amino acid, and a water-soluble amino acid alkali salt;
- and
- a tritium substitution process of circulating fine bubbles in the tritium-containing water in which the organic substance has been added, to enhance an ionization state of ionized molecular species on an air-liquid interface of the fine bubbles and improve contact efficiently between tritium and the organic substance, and causing a reaction of substituting hydrogen in an α position of a carboxylic acid group by tritium in the tritium-containing water, to produce a tritium-substituted product.
