Abstract

Changes in structural characteristics of humic and fulvic acids (HA and FA) were studied during the composting of wastewater of slaughterhouse with lignocelluloses wastes, such as sawdust and grass. Humic substances were extracted by NaOH, purified and dialysed. Freeze-dried humic substances were characterised by UV and EPR (electron paramagnetic resonance) spectroscopy and size exclusion chromatography (SEC). UV spectra were described by absorbance ratios: E 2/E 4, E 2/E 3, E 4/E 6 and E 2/E 6. The results indicated the difference between chromophore systems of compost FA and HA. The average molecular weight of HA decreased, while the molecular weight of FA did not change significantly during composting. There was a good correlation between E 4/E 6 and compost HA molecular weight. The ratios E 2/E 4 and E 3/E 4 for both FA and HA showed high correlation with main EPR parameters such as spin concentration, extent of conjugation and line width.
