摘要
介绍新一代X射线荧光分析仪(XRF)在野外现场矿产勘察中的应用效果。讨论了XRF中的原理和现场勘察中基体效应、湿度效应和不平度效应等主要影响因素。在新一代手提式多元素X荧光仪中,现场X荧光仪对铜、锌、砷等元素的检出限为10×10-6。在野外土壤、岩石的原位分析、异常追索查证等方面具有重要的作用,实践证明,X荧光技术是一种快速、经济、有效的方法。
Introduce the application in the mine exploring of field on-the-spot with X ray fluorescence analysis instrument （XRF） of new generation. Discuss the principle of XRF and influence factors while exploring on live mainly： base matrix effect , moisture effect and roughness effect , etc.. It is proved through the experiment that the detection limits of copper , zinc and arsenic are 10 10^-6 in a portable many -element X-ray fluorescence appearances of new generation. In the aspects of soil of field , normal position of rock analysis and demand of investigating and verifying etc, it has important function. It comes to a conclusion that the XRF technology is a fast economic and efficient geological method.
