| Abstract: | The partition equilibrium of Er(III) between H2SO4 and HEH(EHP) (2-ethylhexyl 2-ethylhexylphosphonate) (HL) in octane was studied. The extration reactions of Er(III) were determine at different acidities. The solid complex of ErL3.mH2O species was isolated. The IR and NMR spectra of the extracted complex were determine |
