    • Abstract
  • The composites of graphene oxide-4 A molecular sieve (GO-4 A) were prepared by ultrasonic and magnetic stiring method. The graphene oxide composites were characterized by X-ray diffraction analysis (XRD), Fourier transform-infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). The effects of component ratio (i.e., the mass fractions of graphene oxide and 4 A molecular sieve in GO-4 A composites) on the adsorption of copper ions were studied. The results show that, the influence of component ratio on the phase composition of GO-4 A composites is limited. With the increase in 4 A molecular sieve content, the aggregation degree of graphene oxide is decreased, and the thermal stability of GO-4 A composites is improved. When the component ratio is 1:5, the composite effect achieves the best, the removal of copper ions (Cu2+) is up to 98.42% at the room temperature and pH = 6.
