Abstract: Liquid membranes are made by forming an emulsion of two immiscible phases and then dispersing the emulsion in a third phase (continuous phase). This is a preliminary experiment on removing chloral hydrate from waste water (50-200ppm) with emulsified liquid membrane, i. e. NaOH solution in kerosene. Some conditions which may influence the permeability have been examined. Under proper conditions, more than 95% of chloral hydrate can be eliminated. And the overall transfer coefficient of the membrane has been calculated. The result shows that it tends to a constant.

摘要： 本工作是用乳状液膜法处理三氯乙醛废水的初步实验.实验系将氢氧化钠水溶液包以煤油作为液膜,处理含有50—200ppm的三氯乙醛水溶液.实验考察了影响三氯乙醛渗透的一些因素,在适当的条件下可以脱除95%以上的三氯乙醛.并计算了该液膜体系的总包传质系数,结果表明它趋向于一个恒定值.
