Lattice-layer materials for column chromatography in dioxin methods

Abstract Three lattice-layer materials were identified and screened for potential use in the cleanup of extracts for dioxin analysis. Determination of the elution profiles of chlorinated dioxins, furans, and diphenylethers on these materials was conducted. Based on these investigations, one of the materials, molybdenum disulfide, was selected and compared with Carbopack C and AX-21 carbon for the cleanup of two contaminated soil samples. The results obtained indicate that molybdenum disulfide is effective for the removal of diphenylethers and other interferences and should be further evaluated for potential use as a chromatographic medium for the cleanup of extracts for dioxin analysis.
