Organic geochemistry of sewage sludge. I. Lipid fractionation by thin layer chromatography
Résumé
This article reports detailed procedures : 1) to decrease organic contamination of samples in the laboratory; 2) to extract sewage sludge with methylene chloride; and 3) to fractionate extracts by silica-gel thin layer chromatography (TLC) into fractions enriched in alkanes, aromatic hydrocarbons, ketones, alcohols and fatty acids, eluting either hexane or methylene chloride.
