摘要：

Algogenic organic matters (AOM) generate from two parts, that are extracellular organic matters (EOM) and intracellular organic matters (IOM). This paper compared the structural characteristics of IOM and EOM originated from Microcystis aeruginosa using techniques including ultra violet-visible spectrum (UV-VIS), Fourier infrared spectrum (FT-IR) and three-dimensional excitation emission matrix (EEM) fluorescence spectroscopy. The results demonstrated that concentrations of the organic matter in EOM were less than that in IOM. EOM has less characteristic absorption peaks. There were more aromatic ring compounds, more protein and amino acids in IOM than EOM.
