▎ 摘　　要

NOVELTY - Washing and separating graphene from graphite oxide comprises (i) washing graphite oxide with detergent, where the detergent includes 15-30 wt.% water, 30-55 wt.% acetone, 10-20 wt.% tween and 20-30 wt.% cyclohexane; (ii) carrying out solid-liquid separation by centrifuging; and (iii) repeating the washing and separating process, to obtain the final product. USE - The method is useful for washing and separating graphene from graphite oxide (claimed). ADVANTAGE - The method has simple procedure; and suitable for large scale production.
