Abstract
The extractability of molybdenum in an aqueous phase by methyl ethyl ketone (MEK), methyl isobutyl ketone (MIBK) and methyl isopropyl ketone (MIPK) were analyzed using inductively coupled plasma atomic emission spectroscopy (ICP-AES). The pseudo-ternary LLE data are reported for the following systems at 298.15 K: {aqueous sulfuric acid solution (ASAS) + MEK + tri-hexyl tetradecyl phosphonium chloride ([P666,14][Cl])}, {ASAS + MEK + tri-hexyl tetradecyl phosphonium dicyanamide ([P666,14][DCA])}, {ASAS + MEK + tri-hexyl tetradecyl phosphonium bis(2,2,4-tri-methylpentyl) phosphinate ([P666,14][TMPP])}, {ASAS + MIPK + [P666,14][Cl]}, {ASAS + MIPK + [P666,14][DCA]} and {ASAS + MIPK + [P666,14][TMPP]}. The experimental LLE data have been correlated using the non-random two-liquid (NRTL) activity coefficient model.
