ABSTRACT

The solid-liquid equilibrium (SLE) for selective solvents, used in the extraction of molybdenum (Mo) from acidic media of Mo ore, has been determined by visual method. The measured SLE data of the systems, trioctylamine (TOA) + 1-octanol, TOA + 1-decanol, and TOA + tributylphosphate (TBP), were correlated by the nonrandom two-liquid (NRTL) and universal quasi-chemical (UNIQUAC) equations and also compared with the calculated values by the modified universal functional activity coefficient (UNIFAC) equation. In addition, the excess molar volumes (VE) and molar refractivity deviations (?R) data at 298.15 K were determined for the same components. These binary VE and ?R data were correlated with the Redlich-Kister equation. Furthermore, the ternary VE and ?R for the systems TOA + TBP + 1-octanol, TOA + 1-octanol + 1-decanol, TOA + TBP + 1-decanol, and TBP + 1-octanol + 1-decanol are calculated from the correlated binary Redlich-Kister parameters using the Radojkovi equation.
