Mc. Gennaro et al., MULTIMETHOD ANALYSIS IN STUDIES OF CHARACTERIZATION AND DEGRADATION OF MUNICIPAL TREATMENT SLUDGES, International journal of environmental analytical chemistry, 53(2), 1993, pp. 101-114
A characterization of the organic components in municipal treatment sl
udges is developed by the use of different instrumental techniques, na
mely HPLC and size-exclusion chromatography, infra-red spectroscopy, n
uclear-magnetic resonance spectroscopy, inductively-coupled plasma ato
mic-emission spectroscopy, graphite-furnace atomic-absorption spectros
copy and thermogravimetric methods. In particular, degradation effects
undergone by sludge along time when preserved in aerobic conditions a
re investigated. A correlation between organic components and heavy me
tals mobility is attempted.
