To characterize the complexing of Db relative to that of its homolog Pa, the extraction of protactinium with Aliquat 336 (methyl-tri-caprylyl ammonium chloride) in toluene from HCl and mix HCl-0.03 mol/l HF media was investigated by a radioactive tracer technique. The distribu-
To characterize the complexing of Db relative to that of its homolog Pa, the extraction of protactinium with Aliquat 336 （methyl-tri-caprylyl ammonium chloride） in toluene from HCl and mix HCl-0.03 mol/l HF media was investigated by a radioactive tracer technique. The distribu-tion ratio D was determined as the ratio of the radioactivity of the organic and the aqueous phases.
