Description

The extraction of Uranium (VI), Thorium (IV), and Europium (III) from nitric acid solution and ruthenium (III) from chlorine solution were studied using a combination of di-benzyl sulfoxide (DBSO) with tri-n-butyl phosphate (TBP) in Methyl isobutylketone (MIBK). They have been investigated as a function of acid and extractant concentration. The extraction were investigated by distribution ratio and extraction percent measurements. Uranium, thorium and ruthenium are extracted to a significant extent. Europium behavior is very poor. (author)
