Abstract

Orange peel is a commercially available natural fiber with an increasing interest in using it as a raw material in a variety of applications due to its high cellulose concentration in the plant. This research aims to determine the preparation of nanocellulose from orange peel waste by using chemical treatment of acid hydrolysis method. In order to provide the optimum conditions of nanocellulose of orange peel waste which are possessed high crystallinity in their crystal structure by using acid hydrolysis method and the effects of various acid concentrations on the crystallinity index, crystallite size and morphology of cellulose nanocrystals were studied. However, based on the previous study, using orange peel waste there is limited study has been reported on type of acid and optimum acid concentration as a parameter of using hydrolysis method. Therefore, in this study, the process of preparation orange peel waste nanocellulose by using acid hydrolysis method with the best type of acid used sulphuric acid (H2SO4) and hydrochloric acid (HCl), optimum acid concentration 30wt% at constant hydrolysis time (120min) and constant temperature (45°C) is comprehensively studied. From the result obtained, H2SO4 is the best method for acid hydrolysis needed to generate well-dispersed crystalline cellulose with minimal aggregation affect and the optimum acid concentration is 30wt% with 120min hydrolysis time and 45°C temperature with the highest crystallinity index and crystallite size which is 87.69% and 3.19nm respectively. Orange peel waste nanocellulose can be promising green material that fits well with global sustainability design and development trends
