The FWG Website is at www.fwgltd.co.uk This is from the paper 'Improved synthesis of Graphene Oxide' by Marcano et al in ACS Nano. You need:
3g graphite
18g potassium Permanganate
360mL 96% Sulphuric Acid
40mL 75% Phosphoric Acid
3mL 35% Hydrogen Peroxide
400mL DI water as ice
to wash you need
200mL DI Water
200mL 30% Hydrochloric Acid
