Description
Summary:Preparation of nanocellulose from red onion and kepok banana (Musa acuminata x balbisiana) peel waste has been carried out by the acid hydrolysis method using sulfuric acid (H2SO4). This study aims to determine the effect of variations in H2SO4 concentration on particle size and nanocellulose morphology of the two materials. The preparation of nanocellulose was carried out in three stages, namely delignification using 10% NaOH, bleaching using 10% H2O2 and isolation of nanocellulose using H2SO4. The variation of sulfuric acid used is 5, 10, 15 and 20%. The characterisations used are X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). The XRD characterisation results showed that the nanocellulose crystalline phase from red onion peel was present at an optimal concentration of 20% H2SO4 and from kepok banana peels at an optimal H2SO4 concentration of 5%. The results of SEM characterization showed that the nanocellulose morphology of the two materials was relatively lumpy.
