説明
Fluorescence spectrometric analysis, on which attention is increasingly focused as a method to measure dissolved organic matter in river water, was conducted using corrected fluorescence excitation and emission spectra.<br>The authors found that fluorescence from a fluorescence whitening agents (FWA) contained in household detergents is overlaps with fluorescence emitted by fulvic-like organic matter, which is the most characteristic fluorescent organic matter in river water, by decreasing the fluorescence intensity due to sunlight irradiation and comparison with the excitation spectrum. Excitation spectra at emission wavelength (λem) of 430nm were analyzed with the fluorescence intensity at excitation wavelengths (λex) of 320nm, 345nm and 360nm of [DSBP], which was used as the reference material, to determine fluorescence emitted by the fulvic-like organic matter and FWA, respectively. As a result, a strong positive correlation was shown between the fluorescence derived from fulvic-like organic matter (λex : 320nm, λem : 430nm) and [DOC]. Fluorescence excitation spectrometric analysis was useful to evaluating that fulvic-like organic matter is discharged from anthropogenic sources.
