| Abstract | ||
| The study of liquid - liquid extraction of neodymium (III) with N-Acetyl-cysteine that refers by (NAC) had been made. The effect of different parameters on the percent of extraction and distribution rataio such as type of medium , time of equilibration , type of solvent , effect of some cations and anions, effect of redox agents , enrichment extraction , concentration of metal ; reagent, effect of batch extraction, salting out , and effect of temperature . The function of thermodynamic parameter of (ΔH , ΔG , ΔS) were calculated .The stoichiometry of the extraction was determined using two methods mole ratio and job' s methods. It was found to be (M: L) (1:3). The stability constant of complex in mole ratio method was calculated. The study of UV-visible and FT-IR spectra were studied for both the reagent and complex in organic phase. Other physical constant namely such as temperture,melting point and specific conductivity. | ||
