Study of Extraction and Characterization of lignin from different Sources

Plantcellwallscontain lignin, acomplexaromaticpolymerthatisvitalformaintaining structural integrity and resistanceto deterioration. In this work, lignin is extracted and characterized froma varietyofbiomasssources,suchaswoodandagriculturalwaste.Ligninisisolatedusingavariety of extraction techniques, including kraft pulping, organosolv procedures, and enzymatic treatments, with an emphasis on comprehending how these techniques affect yield and characteristics. The structural characteristics and functional groups of the extracted lignin are examined using characterization techniques such as Fouriertransform infrared (FTIR) spectroscopy and nuclear magnetic resonance (NMR) spectroscopy. The findings show notable differences in the molecular weight, solubility, and chemical makeup of lignin obtained from various sources.
