摘要：

A method for the interference-free analysis determination of polychlorinated biphenyl (PCB) congeners in sewage sludge in less than 2 h with quantification limits down to 10-20 ppb (w/w) is presented. Evaluations were made of four different trapping materials for the supercritical fluid extraction of PCBs from sewage sludge. The influence of modifiers at different concentrations and temperatures was studied for different trapping materials with respect to their trapping efficiency with spiked samples.
