摘　　要：A method has been developed for the determination of seventeen 2,3,7,8,substituted congeners of polychlorinated dibenzo-p-dioxins and dibenzo-furans(PCDD/Fs) in material of electrical and electronic equipment—polyvinyl chloride(PVC) using gel permeation chromatography(GPC)/fluid management system(FMS)/high resolution gas chromatography-high resolution mass spectrometry(HRGC-HRMS).Dibenzo-p-dioxins and dibenzo-furans was extracted from samples by Soxhlet extraction,purified by GPC and FMS.Confirmation and quantitative analysis at pg/g level of PCDD/Fs was performed by HRGC-HRMS using voltage selective ion record(VSIR)mode.The recoveries of fifteen isotopically labeled compound solution(LCS) were in the range of 61.9%-91.4%,RSD were in the range of 3.16%-6.01%.The quantitative detection limits of the method for 2,3,7,8-tetrachloro-dibenzo-furan(TCDF) and 2,3,7,8-tetrachloro-dibenzo-p-dioxin(TCDD) are both 0.1 pg/g.A method has been developed for the determination of seventeen 2,3,7,8,substituted congeners of polychlorinated dibenzo-p-dioxins and dibenzo-furans(PCDD/Fs) in material of electrical and electronic equipment—polyvinyl chloride(PVC) using gel permeation chromatography(GPC)/fluid management system(FMS)/high resolution gas chromatography-high resolution mass spectrometry(HRGC-HRMS).Dibenzo-p-dioxins and dibenzo-furans was extracted from samples by Soxhlet extraction,purified by GPC and FMS.Confirmation and quantitative analysis at pg/g level of PCDD/Fs was performed by HRGC-HRMS using voltage selective ion record(VSIR)mode.The recoveries of fifteen isotopically labeled compound solution(LCS) were in the range of 61.9%-91.4%,RSD were in the range of 3.16%-6.01%.The quantitative detection limits of the method for 2,3,7,8-tetrachloro-dibenzo-furan(TCDF) and 2,3,7,8-tetrachloro-dibenzo-p-dioxin(TCDD) are both 0.1 pg/g.
