Extraction of thallium and indium, as the homologues of nihonium, from HCl solutions into hydrophobic ionic liquids was studied. In the presence of NaClO2 as the oxidizing agent, thallium is effectively extracted into all the tested ionic liquids from 0.2 to 5M HCl. In absence of NaClO2, thallium extraction strongly depends on the HCl concentration and no extraction of indium was observed. Using [C(6)mim][NTf2] and [Tbma][NTf2], the thallium/indium separation factors SF(Tl/In)>4x10(4) can be achieved. Hence, the system with NaClO2 oxidizing agent can be considered a candidate for the future studies of nihonium chemical properties.
