Chemometric and Spectroscopic Characterization of Dissolved Organic Matter from Sewage Sludge

摘要：

The aim of the present paper is to show the possibilities of nuclear magnetic resonance (NMR) in liquid state in order to understand the molecular complexity of the soluble organic matter (SOM) extracted from sewage sludge composted in anaerobic conditions. Sewage sludge samples were collected at different municipal wastewater treatment plants in Spain. Monitoring the evolution of the organic matter in the sludge by NMR can be a very useful tool in order to avoid environmental pollution problems. NMR can show molecular information about the composition of the SOM and, in this way, different chemometric tools can offer the possibility of finding markers for the anaerobic digestion of sewage sludge. With an appropriate use of algorithms is possible to resolve the molecular complexity of SOM.
