| Abstract: | The penylethylene was reacted with bromine water,finally it was changed to 1,2-dibromo-phenylethane.Then it was separated with the wide-bore capillary columns FFAP and detected by electron capture detector.Compared with standard examination method for drinking water quality,the sensitivity enhanced 20 times. |
