Abstract
Americium and europium extraction with aliquate-336xOH and 4(..cap alpha.., ..cap alpha..-dioctylethyl) pyrocatechol (DOP) from alkali solutions in the presence of alkylphosphonic complexones (EDTP, DTPP) is studied. It is established that americium and europium are almost completely extracted by DOP solution in toluene from EDTP and DTPP solutions in NaOH concentration range from 2 to 4 mol/l and by aliquate-336xOH solution in cyclohexane from 0.6 mol/l and lower. A considerable difference in distribution coefficients of americium and europium during their extraction with DOP from 2 mol/l NaOH when DTPP is used as complexing ligand. Separation coefficient increases with the increase of DTPP concentration, with the decrease of phase contact time, with the decrease of extractant concentration. The highest separation coefficient (Ssub(Eu/Am)=70) is obtained during the extraction in the system 2 mol/l NaOH-10/sup -2/ mol/l DTPP-0.01 mol/l DOP in toluene.
