Abstract

The PS@+rGO@GO@Fe₃O₄ (PG-Fe₃O₄) hybrid composites for Arsenic removal were successfully fabricated and well dispersed using layer-by-layer assembly and a hydrothermal method. The PG-Fe₃O₄ hybrid composites were composed of uniformly coated Fe₃O₄ nanoparticles on graphene oxide layers with water flow space between 3D structures providing many contact area and adsorption sites for Arsenic adsorption. The PG-Fe₃O₄ hybrid composite has large surface adsorption sites and exhibits high adsorption capacities of 104 mg/g for As (III) and 68 mg/g for As (V) at 25 °C and pH 7 comparison with pure Fe₃O₄ and P-Fe₃O₄ samples.
