%X Algogenic organic matter (AOM) was extracted from blue-green algae (Cyanobacteria) and its characteristics was determined by various methods including high-pressure size-exclusion chromatography (HP-SEC), hydrophobic and hydrophilic fractionation and fluorescence excitation emission matrix (EEM). The results showed that AOM was composed of hydrophilic fraction predominantly, account for 78%. The SUVA of AOM was only 1.1 L/(mg·m). The analysis for relative molecular weight (Mr) demonstrated that organic matter greater than 30 000 accounted for above 40% and mostly was composed of neutral hydrophilic compound. EEM analyses revealed that protein-like and humic substances existed in AOM. A test for membrane filtration exhibited that AOM could make ultrafiltration membrane substantial flux decline, which can be attributed to membrane pore clog caused by neutral hydrophilic compound with larger MW.
