碳气凝胶的制备及其对水溶液中铀(VI)的吸附

doi:10.3866/PKU.WHXB2014Ac13

Abstract

Abstract:

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.

Key words: Graphene/carbon nanotube, Hydrogel, Aerogel, Adsorption, Uranium(VI)
