In this regard, two-dimensional 2D materials are a useful alternative for drinking water treatment via physical/chemical adsorption of arsenic pollutants, favored by their high surface area, high adsorption capacity, and high recovery and reusability . As an illustration, activated carbons and graphene-based materials have been demonstrated as potential materials for arsenic removal removing with a high adsorptive capacity for a large number of compounds (Scheme 1b-c) , where the hydrophobicity, recyclability, and adsorption capacity of nanostructured intrinsic surfaces can be remarkably enhanced by surface treatments and oxidation process .
