摘要: The extraction behavior of thorium(IV) has been investigated with tri-butyl phosphate (TBP) and bis(2,4,4-trimethylpentyl) phosphinic acid (Cyanex272) in kerosene from nitrate medium. effect operating variables including time, aqueous phase acidity (pH), extractant concentration temperature were investigated. This study also examined the synergistic enhancement medium by mixtures TBP Cyanex272 for first time. optimum factor 3.86 was obtained at a Cyanex272/TBP molar ratio 1:4.
