Sažetak
Lignin is one of the main macromolecular substances of the cell walls of wood, its part and chemical composition varies between species. Average percentage of lignin is between 20-40 %. There are several methods to quantify, in this paper the percentage of lignin in abonos (bog- wood) and oak wood (Quercus robur L.) was determined using three methods. Acetyl bromide method and Brauns lignin method which give values of the soluble part of lignin and Klason lignin method which also gives the part of lignin insoluble in acids. The soluble part of lignin for the three mentioned methods was determined by spectrophotometric analysis on a UV/Vis spectrophotometer at predetermined wavelengths, and the insoluble part was determined by filtration using glass fiber filter paper and its ignition. Obtained results of lignin percentages were calculated of absorption values obtained from spectrum and ash mass. Since all methods have certain changes in the structure of lignin, the values of lignin participation also differ, which is confirmed by the obtained results and preeceding research.
