The Korean government has regulated emissions of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in waste water of manufacturing facilities producing chlorinated compounds since 2009. As this regulation has been reinforced in 2013 to 50 pg I-TEQ/L, a large sample volume is required for the analysis of trace amounts of PCDD/Fs in waste water. Liquidliquid extraction (LLE) is used to extract PCDD/Fs from aqueous samples. However, its low efficiency makes it inadequate for analyzing large sample volumes. Here, a disk-type solid-phase extraction (SPE) method was applied to the analysis of dioxin at |
