Solvent extraction mechanism and precipitation stripping of bismuth (III) in hydrochloric acid medium by tributyl phosphate
Tributyl phosphate (TBP) was employed for the Bi(III) extraction from hydrochloric acid medium. The effects of extraction time and material concentration were examined. The replacement mechanism between the anion (Cl − ) and TBP was proposed for extraction. The results show the species extracted int...
