Effect of Sulfuric Acid Concentration on The Physicochemical Properties of Pineapple Peel Cellulose Nanofiber

Abstract

Pineapple peel is a significant agricultural waste in Malaysia, causing environmental issues and high disposal costs. To address this issue, cellulose nanofiber extraction from pineapple peel has been performed to create eco-friendly materials. Acid hydrolysis was chosen due to it is an easy and fast method to produce cellulose nanofiber (CNF) with high yield, better properties, and small particle size. The objective of this study was to determine the effect of different concentrations of sulfuric acid on the yield of cellulose nanofiber and to investigate the physicochemical properties of CNF from pineapple peel.
