A method for decontamination of a liquid effluent including one or more radioactive chemical elements to be eliminated is disclosed. According to one aspect, the method includes The method includes mixing, in a first zone of a reactor, solid particles with the liquid which are able, by co-precipitation, adsorption and/or ion exchange, to capture and retain the radioactive chemical elements. The solid particles settle in a second zone of the reactor. The solids, including the radioactive chemical elements, are then separated from the remaining liquid.
