The PS@+rGO@GO@FeO (PG-FeO) hybrid composites for Arsenic removal were successfully fabricated and well dispersed using layer-by-layer assembly and a hydrothermal method. The PG-FeO hybrid composites were composed of uniformly coated FeO nanoparticles on graphene oxide layers with water flow space between 3D structures providing many contact area and adsorption sites for Arsenic adsorption. The PG-FeO 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 FeO and P-FeO samples.
通过层层组装和水热法成功制备并良好分散了用于去除砷的PS@+rGO@GO@FeO（PG-FeO）杂化复合材料。PG-FeO杂化复合材料由氧化石墨烯层上均匀包覆的FeO纳米颗粒组成，三维结构之间的水流空间为砷吸附提供了许多接触面积和吸附位点。与纯FeO和P-FeO样品相比，PG-FeO杂化复合材料具有较大的表面吸附位点，在25℃和pH值为7时，对As（III）的吸附容量高达104mg/g，对As（V）的吸附容量为68mg/g。
