Separation of selenium and tellurium by reversed-phase paper chromatography with tributyl phosphate as the stationary phase and hydrobromic acid or sodium bromide solutions of various concentrations as the mobile phase, has been investigated. The results may be summarized as follows: Selenium and tellurium may be separated with 1-2 M of hydrobromic acid or 8 M of sodium bromide solutions. The R_F values of both selenium and tellurium decrease with increasing concentration of hydrobromic acid. While the RF values of selenium remain practically constant with various concentrations of sodium bromide solution, those of tellurium decrease with increasing concentration of the latter.
