摘　　要：介绍了高精度便携式X荧光分析仪在安徽泾县金属矿勘查中的应用效果。探讨了EDXRF的原理和现场勘查中基体效应、湿度效应和不平度效应等主要影响因素。高精度便携式X荧光分析仪可直接测定样品组分和目标元素含量,其检出限可达10—200mg/kg,在原位条件下分析精度可达2%—10%。实践证明,EDXRF技术是一种快速、便捷、经济、有效的野外勘查方法。Introduce technology and the application of portable high-precision X-ray fluorescence analyzer for prospecting of metal mine in Jingxian of Anhui province. Discuss the principle of EDXRF and influence factors while prospecting on live mainly, base matrix effect, moisture effect and roughness effect, etc. The component and element＇s contents of samples can be measured directly by portable high-precision X-ray fluorescence analyzer. The detection limits range from 100 to 200 mg/kg, and the precision is 2%-10%. It comes to a conclusion that the EDXRF technology is a fast portable economical and efficient field prospecting method.
