NOVELTY - Preparing glucan modified graphene oxide material involves taking graphene oxide suspension with deionized water, ultrasonic dispersing graphene oxide, and peeling off to obtain oxidized graphene suspension, adding glucan into glacial acetic acid solution to dissolve. The graphene oxide suspension is added and stirred. The system is placed in ultrasonic cleaner for ultrasonic stirring to obtain dispersed brown suspended substances uniformly. The de-ionized water is used to centrifugally wash to neutral, and vacuum filtered. The obtained filter cake is dried in vacuum drying box, crushed and sieved to obtain final product. USE - Method for preparing glucan modified graphene oxide material for adsorbing dyes in wastewater (claimed).
