摘要：
The paper has studied the removal of chloromethanes from aqueous media by the method of vapor-phase extraction. Acetonitrile, ethoxyethane, and hexane were used as extractants. Using the removal from aqueous solutions of methylene chloride, chloroform, and carbon tetrachloromethane as an example it was found that vapor-phase extraction was more effective than gas one. The flow-chart for the removal of chloromethanes from polluted waters by vapor-phase extraction in the flowing mode of the closed cycle for using an extractant has been proposed.
