Abstract

The extraction behavior of La³⁺, Sm³⁺, Dy³⁺, and Yb³⁺ in sodium acetate-acetic acid medium was studied with tri-n-buryl phosphate (TBP) at 60°C using paraffin wax as a diluent. The extraction percentage is greater than 85% in the pH range of 6 to 8. The result of slope analysis method indicates that the compositions of the extracted species is found to be La(TBP)(OH)(Ac)₂ for La³⁺ and Yb(TBP)(OH)₃ for Yb³⁺. The effects of extracting time, the concentration of TBP in the organic phase and salts on the extraction efficiency were also discussed.
