COMPARATIVE STUDY OF EXTRACTION & CHARACTERIZATION OF LIGNIN FROM WET AND DRY COCONUT HUSK

Recently lignin has been the object of a renewed interest because of the need to use raw materials from renewable resources. One such resource is coconut husk, a material usually discarded during the copra extraction process. Due to its high lignin content, coconut husk can be pursued as having a variety of applications. Therefore, it is important to know the approximate structure of coconut husk lignin and those variations introduced by different isolation methods. This work reports extraction and a general characterization of dry coconut husk and wet coconut husk lignin through FTIR. Results of percent yield of lignin obtained from different isolation processes are also discussed.
