title: Characterization of the organic component of a sludge.
abstract: Two sludges of different origin (urban sludge and brewery sludge) have been characterized by fractionating the organic content into five parts (by using acids and bases), followed by multiple-technique examination of each fraction. The techniques used included chemical analysis, thermal analysis, infrared spectrometry and (13)C-NMR spectrometry. This approach successfully distinguished between sludge compositions.
