The extraction mechanism of molybdenum from sulfate system by trialkyl benzyl ammonium sulfate (TABAS) has been studied.The results showed that the extraction rate of molybdenum has a maximum value at pH=2-3.The composition of the extracted complex is [R₃NCH₂-C₆H₅]₃HMo₇O₂₃ as determined by the saturation method and slope method.The extraction mechanism based on UV-VIS spectra and IR-spectra was proved to be an anion exchange reaction as follows: 3[R₃NCH₂-C₆H₅]₂SO₄(o)+2HMo₇O_23^(z)^2-⇌2[R₃NCH₂-C₆H₅]₃HMo₇O₂₃(o)+
- Mechanism of extraction,
- Molybdenum,
- TrialkyI benzyl ammonium sulfate
