The extraction of Co(II), Zn(II), Mn(ll), Fe(Ill), and In(Ill) into heptane containing dinonyl naphthalene sulfonic acid (HD), from aqueous perchloric acid solutions, was investigated with the use of the radioactive tracer technique. The distribution coefficients for M(II) and M(IlI) are inversely second and third power, respectively, dependent upon the hydrogen ion concentration in the aqueous phase, and directly first power dependent upon the HD concentration in the heptane phase. The formation constants of In(III) complexes of glycolate, bioxalate, and Co(ll) complexes of bioxalate were determined by use of HD in heptane as a liquid cation-exchanger. For Co(II) - bioxalate it was demonstrated that the formation constants agree with values obtained by using resinous cation-exchanger. Since the use of liquid ion- exchanger permits an analysis of the aqueous and non-aqueous phases, whereas in resinous cation-exchange experiments it is not convenient to analyze the non- aqueous phase, it is of decided advantage to demonstrate that the liquid ion- exchanger can be used for complex studies.
