| Outline of Final Research Achievements |
Excitation emission matrix (EEM) is a method for discriminating the type of organic matter by detecting fluorescences emitted when an organic substance is irradiated with excitation light.
In this study, with the aim of applying EEM to the analysis of membrane foulant, (1) a database for peak positions of solid EEM analysis was constructed for samples recovered from various waters, and (2) a continuous monitoring test of membrane fouling was carried out using solid EEM. Despite being the same material, it was revealed that the peak positions were different in the liquid and solid samples.
Solid-state EEM revealed organic matter properties related to the progress of irreversible membrane fouling.
