Isolation And Characterization Of Lignin From Alkaline Pretreatment Black Liquor Of Oil Palm Empty Fruit Bunch And Sugarcane Bagasse

Terbatas

Lignin is one of potential biopolymers that can be obtained from pretreatment of lignocellulosic materials. In this study, lignin was isolated from alkaline pretreatment black liquor of oil palm empty fruit bunch (OPEFB) and sugarcane bagasse (SB) by precipitation with hydrochloric acid. The isolated lignins were analyzed for their chemical properties, such chemical compositions, UV absorbances, and FT-IR spectra. The results showed that the ash content of lignin from alkaline pretreatment of SB (16.91%) was lower than from alkaline pretreatment of OPEFB (19.19%), while the Acid Insoluble Lignin (AIL) and Acid Soluble Lignin (ASL) contents were vice versa, 46.23 and 4.00% for the former, and 40.14 and 2.82% for the latter. The empirical formula of the lignin isolates derived from the result of ultimate analysis were C9H13.8764O5.9318 and C9H14.1112O6.4321 for lignin from of OPEFB and SB, respectively. The UV spectra showed that lignin from OPEFB had similar bands with lignin from SB. Both lignin from of OPEFB and SB also had similar FT-IR spectra. Proceeding Asean Cosat 2014, Vol. 1.
