Abstract: Liquid membrance extraction are a new and effective technique for separation of mixtures. They are made by forming an emulsion of two immisicible phases and then dispersing the emulsion in a third phase(the continuous phase). In this paper, we have treated the phenolic waste water, which contains 300-950 ppm of phenol, with liquid membrance, i. e. NaOH solution in oil. In proper condition, 98% of phenol may be removed and the breakage of the emulsion drops are less then 1 % per hour. The overall diffusivities of phenol through the liquid membrance are also calculated and they show to be a constant.

摘要： 液膜是用于混合物分离的一种新型有效的技术。它是由两个不混溶相形成乳液,然后将乳液在第三相（连续相）中分散而成。在本工作中,我们应用在油中含有NaOH溶液的液膜处理了含酚为300—950ppm的含酚污水。在适当的条件下,可以使98％的酚脱除,而乳泡的破裂每小时小于1％。计算了酚通过液膜的总包扩散系数,结果表明是一个常数。
