ResumoThe acid dependence curves of 15 inorganic ions in macroamounts were surveyed for the system of 100% TBP-HC1 and HNO3, and compared with results obtained in tracer work previously reported. In most cases, theKd values measured in a system containing 0.1m/l salt are little different from those determined by radioactive tracers. The acid dependence behavior of ferric and zinc chloride were especially studied with varying metal ion concentrations. Additional experiments were carried out for ferric and zinc chloride in the system of 1 % (w/v) TBPO and 5 % (w/v) TOPO toluene-HCl. In these cases theKd values lowered with increasing chloride concentration.
