The transport of phenol (Ph-OH) andp-nitrophenol (p-NP) through a supported liquid membrane system based on hydrophobic ionic liquids ([BEIM][PF6]) (SILMs) consisting of polyvinylidene fluoride membrane (PVDF) as the liquid membrane support and sodium hydroxide solution as the strippping phase, has been studied. The effects of pH, ionic strength, initial concentration of phenol (orp-NP) in feed phase, concentration of sodium hydroxide in the stripping phase have also been investigated, respectively. The optimum transport conditions of phenol in the SILMs were that pH 3.5, ionic strength 0.2 mol/L, initial concentration of phenol 1.31×10-3mol/L in feed phase, concentration of sodium hydroxide in stripping phase was 0.2 mol/L. The permeability value of phenol under above conditions was 2.0×10-5m/s during the transport time of 120 min. The optimum transport conditions ofp-NP in the SILMs were that pH 5.5, ionic strength 0.2 mol/L, initial concentration ofp-NP 4.90×10-4mol/L in feed phase, concentration of sodium hydroxide in stripping phase was 0.15 mol/L.The permeability value under above conditions was 8.6×10-6m/s during the transport time of 120 min. The kinetic equations that can describe transport of phenol andp-NP through the SILMs were also obtained.
