摘要/Abstract

摘要： 采用乳化液膜法对酸枣壳木醋液进行脱酚，以煤油为膜溶剂，研究表面活性剂种类及体积分数、载体磷酸三丁酯（tributylphosphate，TBP）体积分数、内相NaOH溶液浓度和油内比对乳液稳定性及木醋液脱酚效果的影响，并以脱酚率为响应值，利用响应面法对乳化条件进行优化。结果表明：在表面活性剂T154体积分数8%、TBP体积分数3%、内相NaOH溶液浓度0.6?mol/L、油内比5∶4（V/V）条件下，4?500?r/min乳化20?min，所制乳液稳定性良好，木醋液脱酚率达55.31%。

Abstract: The removal of phenol from wood vinegar prepared from wild jujube seed shell by using emulsion liquid membrane was studied in this work. Kerosene was used as solvent to prepare emulsion liquid membrane. The effects of processing conditions including kind and concentration of surfactant, concentration of liquid carrier (tributylphosphate, TBP), internal phase concentration and volume ratio of oil phase to internal phase on the stability of the emulsion and the removal of phenol from wood vinegar were investigated and these variables were optimized by response surface methodology for improved removal rate of phenol. The use of 8% (V/V) surfactant T154 and 3% (V/V) TBP, an internal phase concentration (NaOH) of 0.6 mol/L, a volume ratio of oil phase to internal phase of 5:4 (V/V) and emulsification for 20 min with stirring at 4 500 r/min were found to be optimal for good emulsion stability. Under these conditions, the removal rate of phenol from wood vinegar solution was 55.31%.
