摘　　要：为实现水体重金属污染的快速检测,设计了一种X射线荧光分析仪,采用ARMS3C6410作为分析仪的控制与数据处理核心,Si-PIN半导体X射线探测器作为检测传感器,使用WXCAT-43TG6#001触摸屏控制分析仪工作和显示测量结果,也可通过USB接口与PC机进行数据通信,可现场快速测试水体中Pb、Hg、Cd、Cr、As、Cu、Ni等重金属的含量。应用结果表明,分析仪的操作简单、工作可靠,实现了水体中重金属种类及含量的快速检测。In order to quickly detect heavy metal pollution in water, the X-ray fluorescence analyzer is designed. ARM S3C6410 is used as control and data processing core, Si-PIN semiconductor X-ray detector is used as detection sensor, WXCAT-43TG6#001 touch screen is used to control analyzer work and display measurement results. PC communicates with the analyzer through USB interface, and the content of the heavy metal in water is tested quickly, such as Pb, Hg, Cd, Cr, As, Cu, Ni. Results show that the analyzer is simple to use, reliable to work and enables rapid detection of heavy metal pollution in water.
