| Abstract | ||
| A study on the liquid-liquid extraction of Neodymium (Ш) with Sodan Black B in chloroform that refer by (SBB) has been made. The effect of different parameters on the percent of extraction & extraction coefficient such as type of medium & time of equilibration ,concentration of metal ion , type of organic solvent , effect of batch extraction , salting out , effect of some cations & anions as common interfering on distribution ration & effect of temperature .The function of thermodynamic parameters of (ΔH,ΔGand ΔS) were calculated .The stoichiometry of the extract species is determined using two methods such as mole ration & Job's method it was found to be (Μ : L) (1 : 3) .The stability constant of complex in the mole ratio method was calculated .Studying the UV-Visible spectra were studied both of reagent (SBB) & extracted complex in organic phase .Other physical constant namely , melting-point , & molar conductivity were measured .At last the new study for determination of Nd (Ш) ion in organic phase was began . | ||
