抄録

The solvent extraction of molybdenum(V), MO₂O₄²⁺ with dithizone into tributylphosphate(TBP), chloroform, benzene, chloroform-TBP was investigated. A 1.01×10^-5 M molybdenum(V) was completely extracted with 3.00×10^-4M dithizone into TBP at pH3.2. When chloroform and benzene were used as solvent, about 48% and 80% of 1.01×10^-5M molybdenum(V) was extracted with 5.00×10^-3M dithizone by a single extraction process, respectively. The optimum pH of the extraction are 3.4 and 2.6 for chloroform and benzene. The molybdenum(V)- dithizone complexes extracted into chloroform and benzene have the ratio of Mo₂O₄²⁺: Dz^-=1:2, where Dz^- shows the acid-dissociated form of dithizone. The increase in the extraction percentage with the TBP content may be ascribed to the synergistic effect of TBP. Molybdenum(V) may be extracted with dithizone into TBP and chloroform-TBP as Mo₂O₄-(Dz)₂(TBP)₂-8TBP.
