The application of nanomaterials to remove arsenic (As) from the water represents one of the 21 most promising remediation methods nowadays. In this study, three active materials, including 22 Y2(CO3)3), ZnO/TiO2, and Fe3O4, with different structural and morphological properties, were 23 evaluated for their As(V) adsorption capacity in contaminated water. Thus, the adsorption 24 behaviour was evaluated, includi...
