Abstract

The isolation of lignin from oil palm empty fruit bunches (OPEFB) has been done. Firstly, OPEFB was immersed in NaOH 2% and 4%. Then, the filtrate was acidified by using H2SO4 5N to obtain the lignin. SEM morphology of isolated lignin showed rough surfaces. While, chemical structures of the lignin were analyzed by using FTIR and UV-visible. Aromatic ring vibrations of the phenylpropene (C9) skeleton appeared at 1600 cm-1, 1515 cm-1, and 1425 cm-1. In addition, the presence of aromatic rings/non-conjugated phenolic groups in lignin structure was observed at 280 nm absorption.
