中文摘要：

石墨烯作为最薄的单层碳原子组成的纳米材料,其良好的机械强度、电子迁移率以及较大的比表面积等已经引起广泛关注。氧化石墨烯由片状石墨氧化制得,由于其表面有大量的含氧基团（-OH,-COOH,-CHO等）,在去除重金属离子、染料、抗生素等方面都有较好的效果,有良好的应用前景。

英文摘要：

Graphene is an atomically thin honeycomb lattice of carbon atoms, it caused wide attention because of superior mechanical strength,electron mobility and high specific surface area. Graphene oxide prepared by graphite oxide, GO has plenty of oxygen - containing groups（ - OH, - COOH, - CHO） and shows excellent absorption capacity for the removal of heavy metal ions ,dyes ,and antibiotics. Therefore,GO has good application prospect.
