NOVELTY - The method for separating graphene quantum dot involves preparing graphene quantum dot dispersion, adjusting pH of dispersion using concentrated acid, adjusting pH value of acidic solution using dilute acid and dilute alkali to reach certain value, centrifuging to obtain supernatant, placing the supernatant in a dialysis bag for post-treatment to obtain neutral screening solution, repeating the process to obtain separate solution of neutral solution at pH. USE - Method for separating graphene quantum dot for nanomaterial separation application.
