摘要：目前我国水环境重金属污染问题严重，其中水环境重金属六价铬 [Cr(VI)]污染日显突出，对人类健康和环境安全造成了严重威胁。近年来，Cr(VI)电化学检测方法发展较快，因其具有检测灵敏度高、检测时间短、表征信息丰富、仪器小型便携化的优点，为水环境Cr(VI)的现场、快速、实时、在线和连续测量等新测量要求提供了技术和条件。从电化学定量分析方法和电极修饰材料两个方面，对国内外水环境中重金属Cr(VI)电化学检测方法研究进展进行了综述，指出该方法在实际应用中面临的主要问题，并提出了未来的发展方向。

Abstract: At present, heavy metal pollution in water environment is an increasingly serious problem in our country. Particularly the pollution caused by hexavalent chromium (Cr(VI)), a kind of heavy metal ions, is becoming extremely outstanding, which poses a great threat to human health and environmental security. Recently, the method of electrochemical detection of Cr(VI) is developed rapidly, and provides technology and facility for new measuring requires, such as on-site, fast speed, real time, on-line, constant measurement and so on, due to its virtues including high sensitivity, short detection time, powerful information, instrument miniaturization and portability. Recent domestic and foreign achievements in analysis methods for electrochemical quanti?cation and the modified electrode materials of Cr(VI) in water environment are commented on in this review, and the problems of this method in practical applications and the developing direction in the future are pointed out.
Keywords: water environment; heavy metal hexavalent chromium; electrochemical detection; modified electrode material
