ABSTRACT:
In a method of decontamination of a radioactive effluent from at least ruthenium, a reduction of the effluent is carried out by adding hydrazine or a hydrazine salt. Precipitates having absorbent and/or coprecipitant properties with respect to radioactive elements are formed in the effluent without any intermediate separation of phases, a cobalt sulphide precipitate being formed for the removal of ruthenium.
