What is the process for washing of GO prepared by "Improved synthesis of graphene oxide"method?

07 January 2016 1 4K Report

I prepared GO by "Improved synthesis of graphene oxide" method.After adding hydrogen peroxide its turns to deep yellow color.now i want to purify the solution to get GO.Any one has idea of it?

Farzaneh Zarifi

The filtrate was centrifuged (4000 rpm for

4 h), and the supernatant was decanted away. The remaining

solid material was then washed in succession with 200 mL of water, 200 mL of 30% HCl, and 200 mL of ethanol (2); for each

wash.
