Abstract: In the present study, an efficient and simple extraction technique was developed for zirconium. Liquid-liquid extraction equilibria of zirconium from different aqueous solutions with furfuryl thioalcohol (FTA) dissolved in different diluents and stripping properties were investigated. Results showed that sulfate ions can significantly improve the extraction efficiency of zirconium. The distribution coefficients were depends upon the pH and media concentrations in aqueous phase. The experimental outcomes recommended that using 10%(v/v) FTA with aqueous phase containing 0.5 mol·L-1 Na2SO4, equilibrium pH 4.0 and equilibrium time 10 minutes resulted in 94.62% extraction of zirconium. According to extraction thermodynamics extraction experiment was exothermic, with ΔH= -39.84 kJ·mol-1 and ΔS= -111.179 J·K-1 mol-1. 1.2 mol L-1 H2SO4 was sufficient for quantitative stripping of zirconium loaded in organic phase.
