A column chromatographic method for separation and concentration of polychlorinated biphenyls (PCBs) and terphenyls (PCTs), and dichlorodiphenyldichloroethylene (DDE) in water was investigated using dodecylbenzenesulfonic acid-bindig polyamide as an adsorbent. One to three liters of tap water doped with PCBs or PCTs at the ppb level was passed through a column and compounds adsorbed were eluted with ethanol. After dilution of the eluate with water, they were extracted with hexane. When determined by the electron-capture gas chromatography, all the componds tested were quantitatively recovered. This method will be applicable to the separation of other non-polar substances in water and waste water.
