The Fluorescence Characterization of Organic Matter Extracted from Humic Acid isolated from South-Bohemian Peat

Popis výsledku v původním jazyce

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
