Isolation and Characterization of Lignin obtained from Calliandra calothyrsus shrub using FT-IR Spectroscopy
Pages : 542-544
To explore and use of woody biomass, lignin was isolated from the stem of Calliandra calothyrsus by the acid hydrolysis procedure, in accordance with TAPPI T 222 om-06 which is standard literature method. This technique is employed frequently as it is relatively rapid and yields a lignin which is free of carbohydrate contamination and of relatively high purity. Lignin isolated by acid is characterized by Fourier transform infrared spectroscopy (FT- IR). The study showed that FT-IR analysis can be used reliably to predict Klason lignin in Calliandra calothyrsus.
