| Abstract: | A method was established to determine 19 polychlorobiphenyl congeners in the soil by gas chromatography with ASE-florisil solid phase extraction column purity. It was discussed that organic-chlorine pesticides interfered the determination. The tests obtained following results： good linearity from 0 ug/L to 100 ug/L; the detection limits of 19 polychlorohiphenyl congeners from 0.06 ug/kg to 0.36 ug/kg; the recoveries of matrixes from 78.6% to 120% ; the RSD from 0.2% to 5.1%. |
