ABS>The extraction behaviors of thiocyanate complex of the lanthanides were studied for the system M/sup 3+//NH/sub 4/SCN/TBP/ diluent. The distribution ratios were measured as a function of pH, temperature, NH/sub 4/SCN, and TBP concentration. The distribution ratios of the lanthanides decrease with increase of hydrogen ion in the aqueous phase because of the extraction of thiocyanate ion into the organic phase. The composition of europium thiocyanate complex extracted into the organic phase is probably Eu (SCN)/sub 3/(TBP)/sub 4/ under the conditions studied. The extraction sequence as a function of the- atomic number is compared with the ion exchange sequence for all the lanthanides except Pm. (auth)
