Abstract
New sampling methods were tested at the outlet of electrostatic precipitator in municipal solid waste incinerators. These methods were based on the modified Method 5 sampling procedure reported by USEPA. The results showed that all congeners of PCDD/PCDF and precursors (CB/CP) except monochlorobenzen (M1CB) were caught at the diethyleneglycol-filled impinger, which was cooled by the ice-bath under 5°C. M1CB was caught at the activated carbon columns.
