The Fluorescence Characterization of Organic Matter Extracted from Humic Acid isolated from South-Bohemian Peat
Original language description
In this work, excitation–emission matrix (EEM) spectrometry was used for the first time to extensively study various organic matter extracted from humic acid isolated from South-Bohemian peat. Humic acid was isolated from South-Bohemian peat (locality Třeboň, Czech Republic). Humic acid was extracted using a procedure recommended by the International Humic Substances Society (IHSS). The peat humic acid (SBPHA) was placed in a cellulose thimble and Soxhlet gradually extracted for 12–50 h using trichloromethane, ethyl acetate, acetonitrile, acetone, n-propanol and methanol as a solvent. The organic matter fractions isolated from the peat humic acids were collected and concentrated by a rotary evaporator. Fluorescence spectra were recorded in aqueous solutions of 10 mg/L organic matter extracts using a FluoroLog luminescence spectrophotometer (Horiba Scientific, New Jersey, U.S.). The pH-value of samples was adjusted to seven using standard phosphate buffer. Total luminescence spectra (TLS) were obtained
