The extraction of molybdenum (VI) from hydrochloric acid solutions by di-(2-ethylhexyl)-phosphoric acid (DEHPA, HX) in kerosene and benzene has been investigated under different conditions. The infrared, nuclear magnetic resonance and electronic absorption spectra measurements were made of the organic extracts. As the results, it is found that the extraction of molybdenum(VI) at low aqueous acidity ([HC1] ≤ 3 mol dm<SUP>-3</SUP>) is governed by a cation-exchange reaction and at higher acidity ([HC1] ≥ 3 mol dm<SUP>-3</SUP>) by a solvating reaction : at low acidity, MoO<SUb>2</SUb><SUP>2+</SUP>(aq) + 2(HX)<SUb>2</SUb>(org)↔MoO<SUb>2</SUb>X<SUb>4</SUb>H<SUb>2</SUb>(org) + 2H<SUP>+</SUP> (aq) ; at higher acidity, MoO<SUb>2</SUb>Cl<SUb>2</SUb>(aq) + (HX)<SUb>2</SUb>(org)↔MoO<SUb>2</SUb>Cl<SUb>2</SUb>·2HX(org). Accordingly the monomeric complexes MoO<SUb>2</SUb>X<SUb>4</SUb>H<SUb>2</SUb> and MoO<SUb>2</SUb>Cl<SUb>2</SUb>·2HX, indicating the coordination number of six for molybdenum as the octahedral structure, are formed in the extraction from aqueous solutions at low and higher acidities, respectively.
