How can i remove unreacted graphite from graphine oxide synthesized by improved Hummer's method?

07 November 2022 0 8K Report

I have synthesized Graphene Oxide according to Improved Hummer's method.

But after adding hydrogen peroxide and water some black particle (graphite particle) have shown as precipitate with dark brown(Graphene Oxide) precepitate.

Any problem if graphite is present?How can i remove this graphite particle?
