SUMMARY

Composition and structural characteristics of dissolved organic matter in river water were compared between tropical (Sarawak, Malaysia) and cool temperate (eastern Hokkaido, Japan) climates. DOM samples were concentrated and purified by using a tangential flow filtration system, Millipore Pellicon Mini2 modules. Molecular size distribution, elementary composition, sugar composition, and fluorescence character...
