A radiochemical survey on the extraction behavior of about sixty chemical elements was performed in 1% TBPO toluene solution and hydrochloric acid system. The distribution ratios between organic and aqueous phases were obtained for 1, though the chemical form or the oxidation state could not be defined unambiguously in several cases, familiar chemical forms were chosen as far as possible. Radioactive tracers were employed for determining distribution ratios, which were obtained by measuring the radioactivities of both phases, respectively. The distribution ratios were very similiar for each family of elements. From relationships between distribution ratios and acid concentration in this system, suitable concentrations can be found for separating a pair of ions chosen arbitrarily. In comparing the acid dependence curves in this system with those in 100% TBPHCI system, remarkable similarities were observed, however, those in 1% TBPO-HCl system showed generally lower values than in 100% TBP-HCl system.
