摘要：

Polychlorobiphenyls (PCBs) have been separated from DDT and its analogs and from the other common chlorinated pesticides by adsorption chromatography on columns of alumina and charcoal. Elution from alumina columns with incresing fractionl amounts of hexane first isolates dieldrin and heptachlor epoxide from a mixture of chlorinated pesticides and PCBs. The remaining fraction, when added to a charcoal column, can be separated into two fractions, one containing the chlorinated pesticides, the other containing the PCBs, by eluting with acetone-diethyl ether (25:75) and benzene, respectively. The PCBs and the pesticides are then determined by gas chromatography on the separate column eluates without cross interference. The method is applicable to samples prepared by multi-pesticide residue methodology and should be applicable to sample extracts prepared for gas chromatography. Recoveries of the PCBs (Arocolors) and the chlorinated pesticides are good and the method is applicable to sedimnt and marine biota samples. © 1978.
