Due to its exceptional properties and potentialities for technological innovations in several fields, graphene ? a single atomic layer of sp2-bonded carbon atoms densely arranged into a two-dimensional (2D) honeycomb lattice ? has been the subject of intense research worldwide since its discovery in 2004. In particular, its remarkably high theoretical surface area has led to explore the feasibility of using nanomaterials related to this new carbon allotrope, such as graphene oxide (GO),reduced GO, and graphene-based nanocomposites, for wastewater treatment. Within this scenario, the present chapter provides an overview of recent research studies and advances concerned with the potential of graphene-based nanomaterials as novel promising adsorbents for the removal of various pollutant species, such as heavy metals, dyes, phenolic compounds, and emerging contaminants, from wastewater. A brief description of main routes to synthesize graphene, as well as attempts to regenerate and reuse the adsorbents loaded with the contaminants after saturation, are also included.
