Abstract:
Graphene and chemically modified graphenes were resolved by micellar electrokinetic chromatography (MEKC) using sodium dodecylbenzenesulfonate (SDBS) as a micelle matrix. Graphene was successfully dispersed in a micellar solution, and a consecutive and broad signal was obtained by the MEKC with a 20 mmol dm⁻³ aqueous SDBS solution for Graphene Nanoplatelets. Chemically oxidized graphene was less retained to the micelle than the Graphene Nanoplatelets by the proposed MEKC, and they were resolved with each other.
