Abstract
TBPO와 TOPO와의 혼합용매(희석제:toluene)에 의한 삼가상태의 4f 희토환원소의 추출에 있어 상승효과(synerigistic effect)가 나타남을 알았으며 이것은 각 단독용매계에 있어서 생성추출되는 M(NO3)3 (TBPO)3 및 M(NO3)3 (TOPO)3 형 외에 M(NO3)3 (TBPO)2 (TOPO) 형이 새로히 추가생성됨을 유인된 것으로 인정된다.

Synergistic effect was observed in the extraction of trivalent lanthanides by the mixed solvent of TBPO (tri-n-butyl phosphine oxide) and TOPO (tri-n-octyl phosphine oxide) in toluene diluent. The reason of the enhancement was verified as mainly due to the formation of new extractable species M(NO3)3(TBPO)2(TOPO) besides of the formation of M(NO3)3(TBPO)3and M(NO3)3(TOPO)3.
