This paper investigates the extraction of transplutonium elements (TPE) and other elements using aliquat-336 and alkylpyrocatechol from strongly alkaline solutions in the presence of complexforming substances. It was shown by the methods of NMR and IR spectroscopy that elements can be extracted from alkaline solutions both in the form of coordination-saturated internal complex compounds and in the form of ionic associates, the anionic portion of which consists either of hydroxo-complexes of the cooresponding metals or their compounds with the complex-forming substance. Together with the TPE and REE the authors also studied the extraction of Fe(III), Ru(III), Zr(IV), Pu(IV), Pa(V), Nb(V), U(VI), Cs(I), and Th(IV) from alkaline solutions.
