Abstract:
A method for simultaneously recovering cesium, strontium, rare earths and actinides from liquid radioactive waste comprising:a) contacting the liquid radioactive waste with a solution of a complex organoboron compound, a substituted or unsubstituted polyethylene glycol, a neutral organophosphorus compound and a diluent,b) separating out an organic phase and an aqueous phase,c) mixing stripping reagents with the organic phase formed in step (b), so that an aqueous phase and an organic phase are formed, wherein the cesium, strontium, actinides and rare earths are extracted into the aqueous phase, andd) recovering or disposing of the cesium, strontium, actinides and rare earths.
