Cocoa pod husk and corn stalk: alternative paper fibres study on chemical characterization and morphological structures

摘要

Due to a shortage of wood source fibre in paper making industry's interest to agricultureresidues fibre as a potential fibre sources in this industry. In this situation, importance has beendeveloping in the paper industry from agriculture residue that will replace the wood fibre. Cocoa podhusk and Corn stalk are agriculture residues, which is good materials for paper production. Theobjectives of this study are to investigate the chemical characterization and surface morphologystructure of these materials. The main components of materials which are cellulose, hemicellulose,lignin and ash content were parameters that involved in determination of chemical characterization inthis study. The determination of chemical composition was accordance to Kurshner-Hofherapproach (cellulose), Chlorine Method (hemicellulose), T 222 om-06 (lignin) and T 2 1 1 om-07 (ashcontent). Scanning electron microscopy was used to observe the surface structure of materials. Fromresults obtained, corn stalk shows the higher amount in cellulose (39%) and hemicellulose (42%)content compared to the cocoa pod husk. In addition, lower lignin content also obtained in Corn stalk(7.3%) rather than that Cocoa pod husk (14.7%). From Scanning electron microscopy images, Cornstalk and Cocoa pod husk contained abundance lignocellulosic and rough surface structure due to theuntreated materials. The result either chemical characterization or surface morphology that obtainedin Corn stalk and Cocoa pod husk fibre wastes can be used successfully as an alternative fibressources in papermaking application.
