The paper presents results of studies on extracting properties of neodecanoic acid (Versatic 10) solutions. Neodecanoic acid was diluted in Exxsol D80 AZ to three concentrations: 7.5, 15, and 30 % (v/v). Tests were conducted using sulphate(VI) solutions of six ions: Zn(II), Ni(II), Cu(II), Co(II), Cd(II), Mn(II) and a nitrate(V) solution of Pb(II). All the aqueous solutions were prepared as 0.1 M concentration. For all combinations of the used solutions (organic and aqueous), direct methods of measuring and recording the pH of the biphasic mixture have been applied. The degrees of ions extraction, depending on equilibrium pH were also presented in the paper. Extraction and stripping isotherms of selected ions and organic phase were plotted for 7.5 and 30 % (v/v) of extractant solutions and Zn(II), Ni(II) and Cu(II) ions.
