不使用NaNO 3的改进Hummers法可以制备与传统Hummers法几乎相同的氧化石墨烯。由于不存在Na+和NO3-离子，这种改性不降低产品收率，消除了NO2/N2 O 4有毒气体的产生，简化了废水的处理。我们还首次开发了一种原型方法，用于对从合成和纯化氧化石墨烯的系统中收集的废水进行后处理。净化后的废水中Mn ~（2+）离子含量低于饮用水标准值。(C)2013爱思唯尔有限公司保留所有权利。
An improved Hummers method without using NaNO3 can produce graphene oxide nearly the same to that prepared by conventional Hummers method. This modification does not decrease the yield of product, eliminating the evolution of NO2/N2O4 toxic gasses and simplifying the disposal of waste water because of the inexistence of Na+ and NO3- ions. For the first time, we also developed a prototype method of post-treating the waste water collected from the systems of synthesizing and purifying graphene oxide. The content of Mn2+ ions in the purified waste water was measured to be lower than the guideline value for drinking water. (C) 2013 Elsevier Ltd. All rights reserved.
