Popis: In the limnological environments, dissolved organic matter (DOM) consists of various organic molecules that come from allochthonous origin (e.g. riverine humic substances) and autochthonous origin (e.g. carbohydrates and proteins), and more than 90% of DOM has not be identified yet because most of organic molecules in DOM are intermediate compounds of biodegradation. Thus to develop a simple method to qualify the water in regards of dissolved organic matter is needed. In this study, we developed the monitoring method for limnetic waters using C_ solid phase extraction and 3D excitation-emission matrix (EEM) spectrometry. The eluent conditions for C_ extraction were examined and the suitable ones were proposed. The coefficient of variation calculated by the fluorescent peak intensities were below 7%, and C_ solid phase extraction was found to be a better way for the pre-treatment of EEM spectrometry.
