Graphene and its derivatives are extensively used in many applications from medical to environmental or electronic applications, as well. The high interest for this kind of materials is due to the extraordinary electrical and mechanical properties, the good biocompatibility and a remarkable specific surface area. From the point of view of environmental applications, two properties are essential: very high specific surface area (can reach 2600m2/g, twice comparing to Single Wall Carbon Nanotube) and the ability of graphene to be oxidized and thus, the hydrophobic backbone and the hydrophilic moieties can selectively bind the desired hazardous compounds from different media, regardless their hydrophobic or hydrophilic nature. Among the many preparation routes presented in the literature only a few are suitable for obtaining graphene and graphene oxide at reasonable price at large scale. Along with the ability of selectively remove different species, graphene and its derivatives can be used as sensor.
