Abstract
Lignin is a biopolymer usable in many ways once it has been separated and delignified from biomass. In this training report, delignification of coconut husk fibres is performed, with the aim of recovering isolated lignin. In order to do so, different processes are carried out (autohydrolysis, dilute acid, organosolv and soda pulping treatments). The obtained lignin is characterised afterwards through Fourier transform infrared (FTIR), 1H and 13C nuclear magnetic resonance (NMR) in order to check lignin presence and quality. Analyses show that lignin is indeed obtained in both experiments, though the yield is greater for the treatment with autohydrolysis. However, the global yield is quite low, adjustments of experimental parameters (time, temperature, ratio) shall be carried out.
期刊介绍：
The aim of the journal is to disseminate latest scientific ideas and findings in the field of physical sciences among scientists in Malaysia and international regions. This journal is devoted to the publication of articles dealing with research works in Chemistry, Physics and Engineering. Review articles will also be considered. Manuscripts must be of scientific value and will be submitted to independent referees for review. Contributions must be written in English and must not have been published elsewhere.
