A novel copper ferrite foam fabricated on Fe-Ni foam substrate was synthesized via a simple hydrothermal method to efficiently remove arsenic from aqueous solution. Scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), X-Ray diffraction pattern (XRD) and Raman spectra were used to characterize the morphology and surface composition of the copper ferrite foam (CFF). The adsorption behavior of As(III) and As(V) onto this CFF is studied as a function of solution pH, temperature, contact time, and different concentrations. Results shown that this CFF has high adsorption capacity and excellent recyclability. Adsorption isotherms study indicates Langmuir model of adsorption. The maximum adsorption capability of As(III) and As(V) on CuFe₂O₄ foam is observed about 44.0 mg g^-1 and 85.4 mg g^-1, respectively. Regeneration experiment indicates that arsenic could be easily desorbed from CFF with 0.10 mol L^-1 NaOH and the high adsorption capacity can be maintained for six regeneration cycle.

通过一种简单的水热法合成了一种在Fe-Ni泡沫基体上制备的新型铜铁氧体泡沫，以有效地去除水溶液中的砷。使用扫描电子显微镜（SEM），X射线光电子能谱（XPS），X射线衍射图谱（XRD）和拉曼光谱来表征铜铁氧体泡沫塑料（CFF）的形貌和表面组成。研究了As（III）和As（V）在该CFF上的吸附行为，它是溶液pH，温度，接触时间和不同浓度的函数。结果表明该CFF具有高吸附能力和优异的可回收性。吸附等温线研究表明了Langmuir吸附模型。As（III）和As（V）在CuFe ₂ O ₄上的最大吸附能力观察到分别为约44.0mg g ^-1和85.4mg g ^-1的泡沫。再生实验表明，使用0.10 mol L ^-1 NaOH可以很容易地从CFF中解吸砷，并且在六个再生周期中都可以保持高吸附容量。
