水质中重金属类物质的含量是评价水质污染的重要指标。重金属摄入过量会对人体造成健康危害。当前检测重金属污染的常用方法是原子吸收分光光度法,虽优点多,但样品前处理复杂、检测时间长、需要大型仪器且不能实现现场检测;针对环境及饮水质量检测样品数量大而且需要实时监 The content of heavy metals in water quality is an important index to evaluate water pollution. Heavy metal intake will cause health hazards to the human body. At present, the common method for detecting heavy metal pollution is atomic absorption spectrophotometry. Although there are many merits, the sample preparation is complicated and the testing time is long, which requires large-scale instruments and can not achieve on-site testing. In view of the large quantity of environmental and drinking water quality testing samples and the need of real-
