In this paper we have investigated the behaviours of the reversed-phase thin-layer chromatography and the solvent extraction of selenium and tellurium together with the salting-out effect for tellurium in the reversed-phase thin-layer ohromato-graphy and the solvent eatraotion in P₃₅₀-HBr system. The oomposition of the extracted complex and the apparent extraction equilibzium constant of tellurium were determined.
