| Popis: | The article proved the effects of urea treatment on the structure and properties of wheat straw, using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), contact angle analyze (CAA) and thermal gravimetric analysis (TGA) other methods. The results show that the urea treatment of wheat straw epidermis and lignin chemical structure has undergone significant changes, most of the inorganic components of wheat straw has dissolved, making the cellulose from the lignin parcels released while the lignin from hard degradable mesh macromolecules into small molecules of a straight chain of easily biodegradable, so that the anaerobic microorganisms to the degradation of cellulose and lignin can be more easily. |
