More Information
Summary:The present invention relates to a method of producing nanocellulose from sugarcane bagasse (SCB) comprising the step of subjecting the SCB to sodium hydroxide treatment for partial separation of lignin and hemicellulose therefrom; bleaching the pre-treated SCB with hydrogen peroxide solution for further removal of lignin and hemicellulose to obtain cellulose; ultrasonicating the cellulose to obtain nanocellulose; and hydrolyzing the nanocellulose with 0.1 to 1% (v/v) of sulphuric acid solution to obtain nanocellulose with an aspect ratio of 100-150.
