Аннотация:It was revealed that the oxidation process for natural and synthetic graphite sources proceeds in different ways. The determining factors for the structure and properties of GO are the degree of crystallinity and the lateral size of graphite flakes. The sorption activity of underoxidized, normally oxidized and overoxidized GO was studied toward the methylene blue (MB) dye in aqueous solutions. The most efficient results were obtained for underoxidized and overoxidized GO produced from synthetic graphite. The sorbents removed 94% and 100% of MB from the solution, respectively, in approximately 10 minutes. Our results reveal that the structure and sorption properties of GO can be tuned by varying the oxidation degree as well as graphite source, which may open the way to new developments in the designing new membrane filters for water treatment.
