Then the scope of study includes 1)Extracting lignin from EFB via ultrasonication, 2) Synthesising the EFB retarder using the hydrolysis and sulfonation method and 3) Characterising the EFB retarder via scanning electron microscopy (SEM. The results for SEM (2.67 μm particle size), TGA (75°C thermal stability increase), FTIR (functional group retention), and GC-MS. Results confirmed lignin extraction and successful synthesis of thermally stable retarders Faculty of Chemical and Process Engineering Technology Dissertations Universities and colleges Dissertations Theses Dissertations https://umpir.ump.edu.my/id/eprint/48088 lcc PSM 0 0 lcc 0 0 10000 10000 2026-08-06 0 FTKKP .W38 2025 r Bc.
