Method of removing ruthenium contamination from radioactive effluents

摘要

A method of removing ruthenium contamination from a radioactive liquid effluent, wherein: (a) the pH of said effluent is adjusted to a value of less than 5 and copper ions are added thereto, (b) the effluent thus treated is brought into contact with iron to form a copper precipitate which entrains the ruthenium, and (c) the liquid effluent is separated from the sludge formed.
