Abstract
A self-assemble nanocomposite of the nano-Fe3O4 and the reduced graphene oxide with D-glucose as thereductant and FeCl3 and graphene oxide as the pristine materials was prepared by an one-pothydrothermal method. The adsorption capacity of arsanilic acid by the nanocomposite was found to be313.7 11.2 mg g 1, reach the equilibrium within 15 min, and was independent of pH (3–6) and theconcentrations of ammonia nitrogen up to 1000 mg L 1. The adsorption of arsanilic acid followed pseudosecond-order kinetic model and Langmuir isotherm and was an endothermic and spontaneous process.
