Jasveena R.Prabhagaran Study on delignification of fiber on the temperature and naoh added concentration by ultrasound assistance / Jasveena a/p R.Prabhagaran Kuantan, Pahang : UMP, 2013 xiii, 63 p. : ill. ; 30 cm. + 1 CD-ROM Project paper (Bachelor of Chemical Engineering) -- Universiti Malaysia Pahang – 2013 Bibliography : p. 62 Oil palm is one of the most important industries in Malaysia which leaves behind huge lignocellulosic material as waste product. This product has high percentage of lignin which can be used to make different materials and composites. This research aims to study on the suitable method to determine amount of lignin in fiber and to study on sonokinetic method on delignification of fiber. Fiber was subjected to raw material preparation and followed by material characterization using Klason-Lignin method. Delignification was carried out using ultrasound method and the samples were subjected to Fourier Transform Infrared Scpectroscopy (FTIR), Tensile Strength Analysis and Lignin Test for analysis of the results obtained. It is expected to produce more than 15% of delignification of fiber from the research.
