ABSTRACT:
Halogenated hydrocarbons, such as 1,1,1-trichloro-2, 2-bis(chlorophenyl) ethane (DDT) and polychlorinated biphenyls (PCB), are removed from aqueous media including waste water from chemical manufacturing operations by contacting the aqueous media with an effective amount of a polyolefinic microporous adsorbent, preferably in the form of a filter or cartridge.
