[Abstract]:Emulsion membrane method was used to remove phenol from jujube husk wood vinegar. The kinds of surfactants and the volume fraction of tributyl phosphate (tributylphosphate,TBP) were studied with kerosene as the membrane solvent, and the volume fraction of tributyl phosphate (tributylphosphate,TBP) as carrier was studied. The effects of the concentration of NaOH solution and the ratio of oil to oil on the stability of emulsion and the removal of phenol from wood vinegar were studied. The emulsification conditions were optimized by using the response surface method (RSM), taking the removal rate of phenol as the response value. The results showed that the emulsion prepared by emulsifying 20 min, at 4 500 r/min at the concentration of 0. 6 mol/L, and 0. 6 mol/L, of the concentration of the inner phase of the NaOH solution was stable, and the removal rate of phenol from the wood vinegar was 55.31 at the condition of surfactant T154 volume fraction of 8 and TBP volume fraction of 3, and the concentration of the inner phase NaOH solution was 0. 6 mol/L, in oil, which was better than 5:4 (V / V).
