The graphene oxide/silica composite (GOS) was fabricated using graphene oxide (GO), ethylsilicate (TEOS) as the raw material, oxygen polyoxyethylene-polypropylene-polyoxyethylene (P123) as the surfactant. Through a static test, different experimental parameters, such as solution pH, dosing, initial concentration and contact time, were examined to investigate their effects on adsorption of uranium by GOS. The composite was investigated by FTIR, XRD, SEM and EDS. The results show that the optimal pH, addition, adsorption time are 6, 0.2 g/L and 120 min, respectively. The equilibrium data fit wel...
