[FT-IR characterization of extracted organic phase containing D2EHPA-lanthanide complexes and effects of adding
Abstract:
FT-IR spectroscopy was used to characterize the extracted organic phase of di (2-ethylhexyl) phosphoric acid-n-heptane containing lanthanide ions Ln3+ (Ln: Y, Pr, Nd, Eu ). It was found that the coordination interaction of heavy lanthanide ions with D2EHPA is stronger than that of light lanthanide ions, and saponification percentage of D2EHPA affects both the absorption frequency and the intensity of P=O bond in the extracted organic phase. Furthermore, the addition of di (1-methylheptyl) phosphoric acid to the D2EHPA extraction system leads to the variation of both peak position and intensity of P=O bond.
