摘要：

BACKGROUD: In this work, graphene oxide (GO) was synthesized followed by a modified Hummers method and several characterization techniques were provided. Its adsorptive activity was evaluated based on the removal of Cu(II) from an aqueous solution. External influences were taken into account to further study the adsorption mechanism. RESULT: Characterization results revealed that GO was well prepared and a large amount of oxygen-containing functional groups were introduced. The Cu(II) adsorption increased with increasing solution pH and precipi...
