This article reports the comparison of different chemical methods to produce graphite-based particles with varying degrees of oxidation as well as graphene oxide (GO) and pristine graphite (PG). Detailed physico-chemical characterization of the resulting materials was carried out, highlighting structural differences and variable oxygen content. The particles were then used to produce supported membranes, which were tested for the rejection of three different organic dyes (Rhodamine B, Methyl Blue and Congo Red), and their performance was rationalized in terms of a combination of properties of the membranes and dyes. In particular, membranes produced using edge-oxidized graphite (EOG) showed comparable performance to those derived from GO in the removal of Congo Red, providing a promising alternative to the aforementioned.
