Conclusions

  1. 1.

    The tetraethyldiamide of heptylphosphoric acid in benzene extracts Sc, Th, and Zr from HClO4 solutions in the presence of the thiocyanate ion.

  2. 2.

    On the basis of the graphical and analytical data it was established that complexes with the composition Sc(SCN)3·3DAHPA (pH 1), Sc(OH)(SCN)3·3DAHPA (pH 2.5), Th(SCN)4·2DAHPA, and Zr(OH)2(SCN)2 ·2DAHPA exist in the organic phase.
