| Research Abstract |
Organic fractions separated from Lake Biwa surface water were subjected to C18 and XAD SPE to be analyzed by Excitation-emission matrix (EEM) fluorescence spectroscopy, ^<13>C Nuclear Magnetic Resonance (NMR) spectroscopy, and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). C_<18>-DOM appeared to be rich in polysaccharides. From FT-ICR MS analysis, lignin-like molecules were found to be a main component of the both of C18 and XAD-DOM fractions.
