The chemical structure of lignin, that is, the monolignols and their linkages, is dependent on the biomass type and the procedure used for lignin isolation. The resulting structural differences also influence the lignin's properties such as antioxidant and antimicrobial activity, which are here ...

and the total number of carbonyl groups is 0.019.Eucalyptus leaves lignin has strong absorption at 278 nm and 251 nm in the UV spectrum.Analysis through infrared spectroscopy and 1 H-NMR spectroscopy show that the molecular structure of the lignin contains a large number of hydroxyl,methoxy ...
To investigate the potential for the utilization of cotton stalk, ammonia hydrothermal treatment was applied to fractionate the samples into aqueous ammonia-soluble and ammonia-insoluble portions. The ammonia-soluble portion was purified to yield lignin

Structural and thermal characterization of lignin was carried out through Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC) and thermo-gravimetric analysis (TGA). FT-IR measurements of extracted lignin samples were taken using Shimadzu FTIR 8400s equipped with MIRacl...
