摘　　要：离子传感器的检测对象主要是在水中痕量存在的、但对人体健康或生态环境有重大影响的离子。石墨烯独特的热学、电学与机械性质使得其在离子传感领域受到广泛的关注。目前,人们通过对石墨烯进行修饰和功能化,得到了石墨烯的诸多衍生物和相关的复合材料,满足了不同条件下的传感要求。本文主要选取了石墨烯及其衍生物在Hg^(2+)、Pb^(2+)、Cu^(2+)、K^+等传感中的应用进行了简要介绍,对这些石墨烯及其衍生物基离子传感器的传感机理进行了概括性说明,并对石墨烯及其衍生物基离子传感器的发展趋势进行了展望。Ion sensors are made for detection of ions that are trace in water but are of great influence to healthy or ecological environment. Graphene, with its unique thermal, electrical and mechanical properties, has aroused widespread attention in ion sensing. Graphene with its derivatives and composites can be modified and functionalized to meet various requirements in ion sensors. In this paper, the recent progress of graphene-based ion sensors for detection of ions like Hg＋ , Pb2＋ , Cu2＋ , K＋ , etc were reviewed. The future development of graphene-based ion sensors were also prospected.
