Existing solid phase extraction membrane disk methods were adapted for the analysis of polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF) in industrial effluent and surface water samples containing particulate matter. Particulate matter and suspended solids in a sample were prevented from plugging the disk by placing several types of filtering media in layers on top of the disk, so allowing an entire sample to be extracted without the need for pre-filtering, PCDD and PCDF could then be eluted directly from the filtering medium. Solid phase extraction and liquid/liquid extraction were equivalent statistically, but the former was quicker and less labour intensive.
