ABSTRACT
We propose a method to extract Sr-90 from high-level liquid waste (HLLW) using N,N,N',N'-tetraoctyl as the extractant and tri-n-butyl phosphate as the phase modifier. The process was tested with real HLLW with a recovery percentage of 99.91% of Sr-90. The results show that the proposed process for Sr extraction is efficient in the treatment of commercial HLLW and separation of Sr-90.
