Effect of Chemical Treatment on Kankan Bile Fiber for Composite Production

Abstract: Natural fiber from plant was chemically treated to expose the cellulose contents that gave stronger bonding during reinforcement for composite production. Chemical treatment of Kankan bile fiber was done using three different alkaline solutions; Potassium Hydroxide, Nitric acid, and Acetic anhydride. Optimization of process variables was done to get the optimum condition of the process and model equation was developed. The result showed that nitric acid gave the lowest value of 23.81% lignin removal at 10% concentration, 70minutes and 40OCand highest value of 44.19% removal at 14% concentration, 50minutes and 70OC while Acetic anhydride gave the lowest value of 33.21% lignin removal at 10% concentration, 70minutes and 40OCand highest value of 46.3995% removal at 14% concentration, 50minutes and 70OC. Also, Potassium hydroxide gave the lowest value of 29.89% lignin removal at 6% concentration, 90minutes and 50OCand highest value of 41.24% removal at 14% concentration, 50minutes and 70OC. Hence, acetic anhydride was the best chemical to removal lignin from Kankan bile fiber. Keywords: Acetic Anhydride, Composite, Kankan bile, Natural Fiber, Nitric acid, Potassium hydroxide.
