Abstract

The photo-induced degradation of chlordane, heptachlor and lindane (g-hexachlorocyclohexane) in aqueous ethanol was studied. The degradation was monitored and analyzed by solid-phase extraction using graphitized carbon black and GC-MS. Graphitized carbon black was efficient in extracting these pesticides in30:70 ethanol-water solutions with recoveries ranging from 69% to 109% (SD of 0 to 5). The UV irradiation of chlordane and heptachlor resulted to photodegradation products that were also extracted by graphitized carbon black and detected by GC-MS.
