An analytical method of gas chromatography-triple quadrupole mass spectrometry with accelerated solvent extraction(ASE) was established for the determination of 8 kinds of super trace high chlorinated flame retardants dechloranes in surface soil
including mirex
syn declorane
anti declorane
declorane 602
declorane 603
declorane 604
anti Cl10DP and anti Cl11DP.Soil samples were extracted by ASE with hexane-acetone(1∶1
by volume) mixed solvent at 120 ℃
then on line purified with graphitized carbon black and followed by GCB/PSA solid phase extraction column clean up.The extract was analyzed by GC-MS/MS in MRM mode.The spike recoveries of the method for 8 target compounds in soil at low
medium and high levels ranged from 938% to 107%
847% to 101% and 990% to 108% with the relative standard deviations of 51%-13%
52%-83% and 43%-66%
respectively.The detection limits were in the range of 017-110 pg/g.This method was applied in the analysis on the surface soil samples from some urban and rural areas along the Beijing-Hangzhou Grande Canale.Results showed that the detection rates for 4 compounds ie.syn declorane
anti declorane
declorane 602 and mirex were higher than the others
in which the highest rate reached up to 350%
and the highest concentrations of syn declorane
anti declorane in Huaian were 650 ng/g and 244 ng/g
