Heavy metals are dangerous environmental pollutants. They do not degrade and will cumulate in human body for a long time, causing a variety of diseases. So the quantitative analysis of heavy metals in environmental water is very important. This article describes different methods used for detecting heavy metals in water, and discusses their advantages and shortcomings to provide references for the development of more sensitive, accurate and rapid detection methods.%重金属是环境中较为危险的污染物,不仅不可降解,而且会在生物体内长期积累,引起多种疾病,所以环境水体中痕量重金属的定量分析非常重要.本文介绍了一些检测水体中重金属浓度的方法,分析了各种方法的优缺点,为建立灵敏、准确、快速的检测方法提供参考.
