Özet
Ethylenediamine-N,N'-ditetradecyl-N,N'-diacetic acid (EDDAT) was synthesized for the solvent extraction of $La^{3+}$ . EDDAT was prepared from ethylenediamine-N,N'-diacetic acid (EDDA) and tetrade-cyl bromide in a basic n-amylalcohol-ethanol-water solvent system. The structure of this new extracting reagent was identified according to spectroscopic data, i.e. $^{13}C$ NMR, $^1H$ NMR, and elemental analysis results. The solvent extraction of $La^{3+}$ with EDDAT in dichloromethane was studied as a function of parameters of the aqueous and organic phases. The optimal extraction conditions were determined. The extraction yield increased with a decrease in hydrogen ions in the aqueous phase. Stripping of the $La^{3+}$ loaded organic phase was achieved with HCl aqueous solution. The effect of stripping as a function of the HC1 concentration was also studied.
