摘　　要：水体污染是环境污染的一个主要方式。快速、准确的检测重金属离子已经成为环境保护的一个重要的研究方向。电化学检测法凭借简便、快捷、成本低、可原位检测等特点,成为一种十分重要的重金属离子检测手段。通过改性提高电化学检测中工作电极的敏感性,使工作电极具有更低的检测极限和更宽的检测范围,是电化学法检测重金属离子的研究重点。本文综述了不同改性电极对重金属离子检测的影响,并探讨改性电极对重金属离子检测的增强机制。Water pollution is a major form of environmental pollution.Rapid and accurate detection of heavy metal ions had become an important research field of environmental protection.Electrochemical detection method has become a very important method for the detection of heavy metal ions by virtue of its simple,fast,low cost and in situ detection.Improving the sensitivity of modified electrodes in electrochemical detection,so that they had lower limit of detection and wider range of detection,was the research focus.In this paper,the influence of different modified electrodes on the detection of heavy metal ions has been reviewed and the enhancing mechanism of modified electrodes on the detection of heavy metal ions has been discussed.
