Process for eliminating radioactivity from effluents by liquid-liquid extraction. |
摘要 |
<p>Radioactivity, and especially radium, is removed from an aqueous solution by a process characterised in that the solution is placed in contact with an organic phase containing at least one extractant chosen particularly from the group of fluorinated beta -diketones. After phase separation, a radium-charged organic phase and a purified aqueous phase are recovered.</p> |
