内容記述 | For the purpose of understanding the behavior of protactinium in a perchloric acid solution toward TTA-benzene extraction, the effect of di-isobutyl carbinol (DIBC) on the extraction was studied. A marked synergism was observed. As a result of a detailed investigation of such things as the effects of the TTA concentration, of the DIBC concentration, and of the acidity, the unified mechanism of TTA-benzene and TTA-DIBC-benzene extraction is considered to be a series of successive reactions, (1) through (4), with an increase in the DIBC concentration : PaO_m(OH)^<5-2m-n>_n+4HT=Pa(OH)_2T_3(HT)+(m+n-2)H_2O+(5-2m-n)H^+Pa(OH)_2T_3(HT)→PaOT_3(HT) (slow, irreversible) (1) PaO_m(OH) ^<5-2m-n>_n+4HT+B=Pa(OH)_2T_3(HT)B+(m+n-2)H_2O+(5-2m-n)H^+Pa(OH)_2T_3(HT)B→PaOT_3(HT)B (slow, irreversible) (2) PaO_m(OH)^<5-2m-n>_n+3HT+B=Pa(OH)_2T_3B+(m+n-2)H_2O+(5-2m-n)H^+Pa(OH)_2T_3B→PaOT_3B (slow, irreversible) (3) PaO_m(OH)^<5-2m-n>_n+3HT+2B=Pa(OH)_2T_3B_2+(m+n-2)H_2O+(5-2m-n)H^+Pa(OH)_2T_3B_2→PaOT_3B_2 (slow, irreversible) (4) The slow, irreversible reaction in each step indicates the irreversible formation of unstrippable species in the organic phase with aging. The absorption spectral measurements gave results consistent with this conclusion. | |||||||||
