Sequential Extraction of Organic Fractions from Biochar using Eluotropic Series of Organic Solvents
Original language description
In this work, we performed a sequential chemical extraction with a series of organic solvents with an increasing polarity (trichloromethane – TCM1 < ethyl acetate – EAC2 < acetone – ACE3 < acetonitrile – ACN4 < n-propanol – PRO5 < methanol – MET6) on Czech biochar and subjected the obtained organic fractions to a physicochemical characterization utilizing thermal and spectrometric methods of structural and compositional analysis. Spectrometric techniques such as Ultraviolet-visible (UV/Vis) and Attenuated Total Reflectance (ATR-FTIR) were combined with thermogravimetric and elemental analysis of the organic fractions. Biochar was homogenized and 5000 mg was then inserted in a thimble, and Soxhlet sequential extracted for 24–168 h. The organic fractions isolated from the biochar were concentrated using a rotary evaporator. Furthermore, the brown to black extracts were dried in a vacuum desiccator filled with anhydrous sodium sulphate as a drying medium. In total, the fractionation procedure extracted o
