摘要：

A membrane extraction mass spectrometry (MEMS) technique was developed for the on-line analysis of organic components of multiple liquid and gas streams. Silicone hollow-fiber membranes allow for the extraction of organic chemicals from complex and dirty matrices with no sample preparation. Multiple streams of both air and water were analyzed on-line with a single analyzer. This method has been applied in an aerobic biological wastewater treatment process. Mass balance determinations were performed by quantitatively measuring the organic contaminants in the influent wastewater stream, in the effluent water stream, and in the effluent air stream.
