FTIR spectra
Original language description
The inÍiared spectra of humic acids from peat, soil, coal, oxidized coal, and oxyhumolite were obtained using the diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy. For structural evaluation, three regions of the DRIFT spectra were used: 3800-3100, 3000-2800, and, 1900-1500 cm-1, which corresponds to hydroxyl, aliphatic, and Aromatic/carbonyl/nitro structures, respectively. The band height ratios of the above mentioned bands seem to be suitable parameters for rapid structural characterization of humic acids and raw materials. DRIFT represents an excellent spectroscopy technique for characterizing of humic materials in neat form without alkali halide matrix, which can alter the spectra by ionic exchange reactions with the analyte.
