In aquatic environment, Natural Organic Matter (NOM) is a complex set of variable compounds derived from plants / humus decaying and/or generated from primary production of aquatic microorganisms. Characterisation of NOM properties has always been a challenge for scientist. Nevertheless, some characterisation technics have already provided useful information. In particular, fluorescence spectroscopy has allowed the differentiation of some of the specific components composing NOM. Recent advance in the sensitivity of fluorescence equipment has provided the possibility to measure either dissolved or solid samples, providing a new field for the study of solid NOM properties.
This work describes one application of 3D-Solid Phase Front Face Fluorescence (3D-SPFFF) spectroscopy to characterize some components representative of solid NOM. Thus, fluorescence emission excitation matrix were performed on simple or complex model compounds.
