The ion-pair complex has also quantitative extraction in xylene and 1,2-dichloroethane. Indium(III) from organic phase was stripped with 1.0 M hydrochloric acid and determined complexometrically with EDTA. The stoichiometry of the extracted species was found out on the basis of slope analysis. The extraction of indium(III) proceeds by an anion exchange mechanism and the extracted species is [RR'NH(2)(+)In(succinate)(2)(-)]((org)). Temperature dependence of the extraction equilibrium constant was also examined to estimate the apparent thermodynamic functions (Delta H, Delta G and Delta S) for extraction reaction. It is possible to separate indium(III) from Zn(II), Cd(II), Pb(II), Hg(II), Bi(III), Tl(I), Tl(III), Ga(III), Al(III), Te(IV), Se(IV), Sb(III), Fe(III) and Sn(IV). The method is simple, rapid and reproducible and can be used to determine the indium from samples like alloys.</p>10a2-OAP10aBinary separations10aIndium(III)10aliquid-liquid extraction10aSodium succinate1 aMahamuni, Sandip, V.1 aKolekar, S., S.1 aWadgaonkar, P., P.1 aAnuse, Mansing, A.  uhttps://library.ncl.res.in/content/solvent-extraction-trivalent-indium-succinate-solution-2-octylaminopyridine-chloroform-0
