Abstract

The paper discusses the changes hydro-optical parameters that characterize the qualitative composition of dissolved organic matter (DOM), during fractional filtering though large (4.5 μm and 1.76 μm) and small (0.9 μm) filters. A loess reservoir lake Khanka containing great amount of suspended inorganic matter were selected as the research object. In order to assess changes in the composition of the DOM the following parameters were selected: index of the degree exponent of absorption spectrum, the specific absorption coefficient, relative specific fluorescence yield and relative specific fluorescence,. The research has shown that not only the content of organic matter during adsorption on the surface of the suspension is changing during filtration, but also the composition.
