摘要: Abstract The development of an analytical method for the analysis PCDD/PCDF in flyash using a bench system comprising gas chromatograph fitted with ion trap detector operated tandem MS mode is described. optimum settings most important MS/MS parameters are given, including those less reported mono- to tri-chlorinated dioxin and furan congener groups. Flyash samples from three waste incineration plants representing decommissioned 1970s plant design, upgraded still operating originally designed 1970s, modern 1990s design have been analysed PCDD/PCDF. were methods developed total PCDD/PCDF, I-TEQ values isomeric profiles reported. older incinerator had very significantly higher concentrations compared flyash.
