摘要：

In this work, graphene oxide aerogel (GOA) was synthesized by ice segregation induced self-assembly method. The characterization of GOA was studied by Fourier transform infrared spectroscopy, X-ray diffraction, Raman spectroscopy, transmission electron microscopy, scanning electron microscope, and Brunauer-Emmett-Teller specific surface area. Effects of contact time, pH, and initial concentration on the adsorption capacity of GOA were studied. The adsorption process fitted well with pseudo-second-order kinetic and Langmuir isotherm models with the maximum adsorption capacities for methylene blue and methyl orange of 480.76 and 55.56 mg/g, respectively.
