| Research Abstract |
Photodegradation of dissolved organic matter (DOM) in lake water or its inflowing water were characterized by using the technique of measuring dissolved organic carbon (DOC), UV absorbance, and size-exclusion chromatography (HPLC-SEC) with TOC detector. DOM in lake water was revealed to have the conformation of hydrophobic compounds (like fulvic acid) surrounded by hydrophilic compounds. Those hydrophobic compounds were suggested to have high molecular weight (more than 35,000Da) from the result of HPLC-SEC
