摘　　要：研究了用非流动载体乳状液膜法对废水中的邻甲苯酚进行提取分离,对影响邻甲苯酚渗透扩散的几种因素进行考察。结果表明,油相为10%Span80煤油溶液、料液pH=3.5～5、内水相为2%NaOH溶液和乳水比Rew=1∶10的条件下,经过一级液膜分离过程,邻甲苯酚的提取率可达98%以上,对提取富集的邻甲苯酚还可以进行回收利用。The separation of ortho-cresol from wastewater with emulsion liquid membranes was studied.Some factors which influenced the penetration and diffusion of ortho-cresol were investigated in the separation of emulsion liquid membranes.The experimental results show that the extraction ratio of ortho-cresol is higher than 98% when the oil plase is 10% Span-80 kerosene solution,the pH=3.5~5 in feed,the internal phase is 2% NaOH solution,and R ew=1∶10.The enrichment of ortho-cresol in the internal phase can be recycled.
