Yurdakoc, MHosgoren, H2024-04-242024-04-2419981010-7614https://hdl.handle.net/11468/21631Ethylenediamine-N,N'-ditetradecyl-N,N'-diacetic acid (EDDAT) was synthesized for the solvent extraction of La3+. EDDAT was prepared from ethylenediamine-N,N'-diacetic acid (EDDA) and tetradecyl 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. C-13 NMR, H-1 NMR, and elemental analysis results. The solvent extraction of La3+ 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 La3+ loaded organic phase was achieved with HCl aqueous solution. The effect of stripping as a function of the HCl concentration was also studied.eninfo:eu-repo/semantics/closedAccess[No Keyword]Article224373377WOS:000076728100009Q4
