摘要：
Carbon aerogels were prepared, using a freeze-drying method, from graphene oxide (GO) and carbon nanotube (CNT) hybrid hydrogels. The resulting aerogels were characterized using scanning electron microscopy and Fourier-transformed infrared spectroscopy. The adsorption of U(VI) on the GO-CNT aerogels was studied as a function of solid dosage, pH value, initial concentration, and contact time. The results showed that GO-CNT aerogels have high uranium(VI) removal capacities, and are promising sorbents.
