摘要：

This article presents a study concerning the storage effect on the fluorescence properties of dissolved organic matter fractions, obtained by ultrafiltration. Protein-like peak, gamma, and recent production of organic matter, beta, were evidenced through fluorescence spectroscopy in the 0.5 kDa subfractions, while humic substances, a and alpha', appeared predominantly around 1-3 kDa. Results have shown that storage at 4 degrees C, in darkness, for three months, did not affect the fluorescence properties of water samples.
