摘要：

Organochlorines, including PCB [polychlorinated biphenyls] and DDT in sediment and sludge are determined in the presence of elemental S. The method can also be used for unprejudiced search for both volatile and/or polar pollutants. The S interfering in the gas chromatographic determination is removed in a nondestructive treatment of the extract with tetrabutylammonium sulfite. This lipophilic ion pair rapidly converts the S to thiosulfate in an organic phase. The recovery of added organochlorines was above 80% and the detection limit in the range of 1-10 ppb from a 10 g sample.
