| Research Abstract |
Fractionation methods based on the hydrophobic-and hydrophilic-properties of the DOM, which governs the carbon dynamics in soil and water ecosystems greatly, were developed as new DOM dynamics analysis. By the successive method based on resin adsorption, it found out that the DOM could classify to hydrophilic DOM and hydrophobic DOM, and the latter further to DOM of strong hydrophobic and weak hydrophobic. The usefulness of this facilitated technique was proved through actual analysis of DOM in some of the soils and the lake waters.
