摘要：

Relative efficiencies of various sample preparation techniques were measured for analysis of chlorinated dioxins and dibenzofurans (PCDD, PCDF) in representative wastes. The following sample cleanup columns were tested: a mixed phase column of acid, base, and neutral silica; neutral and acidic alumina columns; Carbopack/Celite and AX-21 carbon adsorption columns. Chlorinated dioxins and dibenzofurans were analyzed in fly ash, still bottom, fuel oil, and sludge matrices for this study. The multi-phase silica, acidic alumina, and AX-21 columns were determined to be the most suitable combination for PCDD and PCDF analytes. © 1990.
